Abstract:
We offer a new method for analyzing the electromagnetic field scattered from the objects. The method is based on calculating the field gradients in the incidence and scattering space in a bistatic radar scheme. The analysis of the differences between the real target and artificial jam-producing object showed the high sensitivity and efficiency of the method used, because the topology of the two-dimensional field scattering gradients pattern varies significantly for these two objects. We detected substantial polarization dependence of the scattered field gradients, which together with the topological portraits of the scattered field itself make it possible to find a new approach to the target discrimination. The analysis we did allows us to develop a target detection strategy for an artificial object by the controlled change of the incident and scattered angles (viewing angles) in accordance with the laws obtained in topological portraits of the gradients of electromagnetic fields scattered over a wide angular range from the objects. Findings of the research could be helpful in developing specific strategies of polarization bistatic radiolocation based on the gradient analysis method.

Abstract:
Based on the analysis of switching devices and various electrical installations, the article shows that their main element is a high-speed electromagnetic device that performs the functions of a reacting organ and a drive. Both a polarized and a neutral electromagnet can be used as such a device. So far, polarized electromagnets have been most widely used as the fastest ones. However, there are a number of designs of neutral type electromagnets that can replace polarized electromagnets, in particular in electric locomotive circuit breakers. An analysis of the state of the problem showed that the methods for calculating and studying high-speed electromagnetic devices require more rigorous and accurate mathematical calculations that allow replacing experimental studies in real emergency conditions and at the same time automating the work of researchers through the widespread use of more accurate calculations. The results of theoretical studies of processes occurring in high-speed electromagnets, mathematical dependencies for calculating parameters and characteristics, both in static and dynamic modes of operation, are presented. An equation was obtained to determine the optimal counteracting force, at which the cycle time is minimal. Mathematical algorithms have been developed for calculating the static and dynamic characteristics of high-speed electromagnets, taking into account steel saturation, leakage fluxes, eddy currents in massive elements of magnetic circuits and current conductors.

Abstract:
In medium voltage vacuum circuit breakers, in order to achieve an even distribution of force along the entire length of the drive shaft, the drive mechanism is made per phase, that is, a separate electromagnet is installed under each pole. The analysis of designs and features of operation of vacuum circuit breakers with a per phase electromagnetic drive is carried out. Deficiencies in the designs of these drives have been identified. The design of a vacuum circuit breaker with a per phase electromagnetic drive and a kinematic diagram of the operation of a vacuum circuit breaker with a monostable polarized electromagnet and a return spring during the closing operation are considered. As a per phase drive, it is proposed to use three monostable polarized electromagnets with return springs, which makes it possible to reduce the overall dimensions of not only the drive electromagnet, but also the vacuum circuit breaker. Moreover, the return spring is not included in the design of the proposed electromagnet, but is part of the circuit breaker drive mechanism. The design of the housing of the vacuum circuit breaker with a per phase drive and a synchronizing shaft has been developed, which makes it impossible for the non-simultaneous closing and opening of the main contacts when performing switching operations. The calculation of a monostable polarized electromagnet is carried out and the possibility of its use as a per-phase drive in a medium voltage vacuum circuit breaker is confirmed.

Abstract:
<p class="1Body">Experiments show that, there is the electrostatic field around the permanent magnet; since the electromagnetics can not explain this phenomenon, it can be concluded that there are some defects in electromagnetics. This paper makes an analysis of the defects of electromagnetics from fourteen aspects. It is noted that, the basic defect of electromagnetics is that there is no explanation of any inherent causes and physical processes of electromagnetic induction, displacement current, Lorentz force and other surface phenomena. Moreover, it may also lead us to make incorrect inferences in the theoretical analysis of electromagnetics, e.g. the same direction of action and reaction, infinitely high kinematic velocity of magnetic field, etc. It can be seen from analysis of all electromagnetic phenomena that, all the electromagnetic phenomena will be inevitably accompanied by an electron motion; and the electron motion is bound to take effect through an electric field; therefore, the analysis of motion in an electric field is the basis for analysis of all electromagnetic phenomena. This paper proposes seven rules for analysis of motion in an electric field, analyzes the uniform motion and variable motion in an electric field on the basis of such rules, clarifies the inherent causes of Lorentz force, theoretically qualitatively and quantitatively demonstrates why there exists the electrostatic field at some locations around the permanent magnet, and considers that all the magnetic phenomena are resulted from the contraction of electric field in the direction of motion, which is derived from the natural law of constant velocity of light, and therefore all the electromagnetic phenomena is rooted in the constant velocity of light. Through the analysis of variable motion in an electric field, this paper proves the law of displacement current and electromagnetic induction, clarifies the physical processes of such phenomena, deduces the law of total current, explains why electric field strength and magnetic field strength of electromagnetic wave must be in same phase and why a plane wave has the electric and magnetic fields only with a certain length but no source, and considers that neither fast nor slow propagation velocity of electromagnetic wave is good and that the actual velocity of light is the ideal velocity of light.</p>

Abstract:
A dynamic model of the bogie of maglev train with distributed magnetic forces and four identical levitating controllers is formulated. The vertical, pitching, and rolling degree of freedom of the electromagnet modules and their coupling are considered. The frequency responses of the bogie to track irregularity are investigated with numerical simulation. The results tell us that there are resonances related to the first electromagnetic suspension whose frequencies are determined by the control parameters. A comparative analysis has been carried out between the models with distributed or concentrated magnetic forces. The comparison indicates that simplifying the distributed magnetic force to concentrated one degenerates the dynamic behavior of the maglev bogie, especially resulting in overestimated resonances of the first electromagnetic suspension of maglev trains. The results also indicate that those resonances only occur on specific wavelengths of irregularity that relate to the length of the electromagnets.

Abstract:
To verify the relationship between AETA (Acoustic and Electromagnetics to Artificial Intelligence (AI)) electromagnetic anomalies and local earthquakes, we have performed statistical studies on the electromagnetic data observed at AETA station. To ensure the accuracy of statistical results, 20 AETA stations with few data missing and abundant local earthquake events were selected as research objects. A modified PCA method was used to obtain the sequence representing the signal anomaly. Statistical results of superposed epoch analysis have indicated that 80% of AETA stations have significant relationship between electromagnetic anomalies and local earthquakes. These anomalies are more likely to appear before the earthquakes rather than after them. Further, we used Molchan’s error diagram to evaluate the electromagnetic signal anomalies at stations with significant relationships. All area skill scores are greater than 0. The above results have indicated that AETA electromagnetic anomalies contain precursory information and have the potential to improve local earthquake forecasting.

Abstract:
In this paper, the structural characteristics of electromagnetic suspension (EMS) inertial stabilizers are analyzed firstly, and then a mechanical analysis of a single mass block and double mass block is carried out. The relationship model between the inertial anti-rolling mass block and inertial force transmitted to the ship is established. The inertial force is determined by the number of coil turns, coil current, mass block, mass of the ship, electromagnet current, rate of change of the electromagnet current, air gap between the electromagnet and inertial mass block, and rotational angular speed. Through theoretical analysis, it is found that the response speed of inertia force is directly related to the electromagnetic coil current, the voltage at both ends of the electromagnetic coil, the coil resistance and the air gap. It is concluded that the response speed of the inertia force can be controlled by controlling the coil current, adjusting the voltage at both ends of the coil and adjusting the air gap. The inductance of the electromagnetic coil will also increase the nonlinearity of the inertial anti-roll system. On the basis of theoretical analysis, a digital simulation of EMS inertial stabilizer is carried out by MATLAB and ANSYS MAXWELL2D. Finally, a single mass block system of EMS inertial stabilizer is designed and tested. During the test, a 1.5 V sinusoidal excitation voltage is added to the electromagnetic coil after the mass block is suspended stably, and the maximum acceleration values of the inertial anti-rolling mass block and hull are 10.29 m/s2 and 1.27 m/s2. Finally, the theoretical analysis results, digital simulation results and experimental results are analyzed, which verifies the correctness of the acceleration and inertia force performance analysis of the EMS inertial stabilizer.

Abstract:
Acoustic and electromagnetics to artificial intelligence (AETA) is a system used to predict seismic events through monitoring of electromagnetic and geoacoustic signals. It is widely deployed in the Sichuan–Yunnan region (22° N–34° N, 98° E–107° E) of China. Generally, the electromagnetic signals of AETA stations near the epicenter have abnormal disturbances before an earthquake. When a significant decrease or increase in the signal is observed, it is difficult to quantify this change using only visual observation and confirm that it is related to an upcoming large earthquake. Considering that the AETA data comprise a typical time series, current work has analyzed the anomalism of AETA electromagnetic signals using the long short-term memory (LSTM) autoencoder method to prove that the electromagnetic anomaly of the AETA station can be regarded as an earthquake precursor. The results show that there are 2–4% anomalous points and some outliers exceeding 0.7 (after normalization) in the AETA stations within 200 km of the epicenter of the Jiuzaigou earthquake (M. 7.0) and the Yibin earthquake (M. 6.0) half a month before the earthquakes. Therefore, the AETA electromagnetic disturbance signal can be used as an earthquake precursor and for further earthquake prediction.

Abstract:
Magnetorheological fluid (MRF) Brake is a newly-developed intelligent brake in which traditional mechanical brake friction pairs are replaced by MRF materials and the electromagnetism devices are very important components. The controllable magnetic fields are generated by electromagnetism devices which can make MRF materials create related braking torque to control the braking performance of the MRF Brake. In this paper, the electromagnetism device consists of several coil sets which can generate electromagnetic fields for MRF Brake. By using finite element analysis, the magnetic fields generated by electromagnetism devices are compared analytically under the different conditions, and then the optimum parameters are obtained such as coil arrangements, excitation currents and air gap distances and etc. All these evidences are helpful to design the structure of electromagnetism devices in MRF Brake.

Abstract:
Terahertz (THz) reflection and transmission spectroscopy is a promising new field with applications in imaging and illicit material detection. One particularly useful application is for the detection of improvised explosive devices (IEDs) which is a favorite weapon of global terrorists. Explosive materials have been shown to have a unique spectral signature in the THz band which can be used to identify the explosives. However, the initial measurements performed on the explosive samples do not account for the modulation of the spectral features by random scattering that will be prevalent with actual samples encountered in applications. The intent of this work is to characterize and quantify the effects of random scattering that may alter the spectral features. Specifically, the effect that a randomly rough surface and granular scattering has on the scattered THz wave (T-Rays) will be investigated and characterized using the Finite-Difference Time-Domain (FDTD) simulation method. The FDTD method is a natural choice for this work as it can handle complicated geometries (i.e., multiple scatterers, arbitrarily rough interfaces, etc.) arbitrary materials (i.e., dispersive media, etc.) and provides broadband frequency data with one simulation pass. First, the effect that the randomly rough surface of the sample explosive has on the extracted spectral signature will be studied using a Monte-Carlo analysis. Then the effect of the complex structure inside the explosive material (the granular scatterers) will be considered. Next, when the physics of the rough surface and granular scattering are understood, a robust method to extract the spectral signature from the reflected T-rays will be developed.

Abstract:
Simulating electromagnetic waves is of increasing importance, for example, due to the rapidly growing demand of wireless communication in the fields of antenna design, photonics and electromagnetic compatibility (EMC). Many numerical and asymptotic techniques have been developed and one of the most common is the Finite-Difference Time-Domain (FDTD) method, also known as the Yee scheme. This centered difference scheme was introduced by Yee in 1966. The success of the Yee scheme is based on its relatively high accuracy, energy conservation and superior memory efficiency from the staggered form of defining unknowns. The scheme uses a structured Cartesian grid, which is excellent for implementations on modern computer architectures. However, the structured grid results in loss of accuracy due to general geometry of boundaries and material interfaces. A natural challenge is thus to keep the overall structure of Yee scheme while modifying the coefficients in the algorithm near boundaries and interfaces in order to improve the overall accuracy. Initial results in this direction have been presented by Engquist, Gustafsson, Tornberg and Wahlund in a series of papers. Our contributions are new formulations and extensions to higher dimensions. These new formulations give improved stability properties, suitable for longer simulation times. The development of the algorithmsis supported by rigorous stability analysis. We also tackle the problem of controlling the divergence free property of the solution—which is of extra importance in three dimensions—and present results of a number of numerical tests.

Abstract:
The purpose of the study is to better understand the factors that affect melt-wear in the armature-to-rail contact interface of an electromagnetic launcher (EML). In order to investigate the factors, the study uses finite element analysis (FEA) to vary parameters of a lab-scale EML at the Georgia Institute of Technology. FEA is used due to the complex nature of the system, which includes the geometry and various engineering aspects that the EML incorporates. The study focuses on an uncoupled analysis of the structural, electromagnetic (EMAG), thermal, and modal aspects. The reason for the uncoupled analysis was because the system was complex and there were computational limits. Also, by uncoupling the analysis fields, the way the parameters affected melt-wear could be viewed separately. The study varied the geometry of the armature, the stiffness of the rail system (compliance layer), and the material of the armature. The structural analysis was for the initial contact of the rail to the armature and found the von Mises stresses, contact area, and contact pressure. The EMAG analysis found the Lorentz forces in the system based on a current curve used in the lab-scale EML. The thermal analysis consisted of friction heating and Joule heating. The modal analysis was for the unstressed and pre-stressed armature. Based on the study conducted, it was found that aluminum would provide the best speeds due to its lighter mass, but lacked in the thermal resistance area. Tungsten provided the better thermal resistance, but lacked in the potential speed due to its heavier mass.

Abstract:
This thesis derives working expressions from electromagnetic physical laws to gain a deeper understanding of the nature of railguns. The expressions are refined for ease of use and then compared to electromagnetic simulators that solve complex equations that arise from different rail geometry. Further simplifications lead to an expression for the final velocity of the projectile and showcase the importance of the system resistance to projectile flux gain ratio. A Simulink simulation then incorporates the resulting non-linear differential equations and approximates the projectile velocity over time based on physical dimensions and material properties. Some equations derived can be found in literature regarding the subject but often lack explanation. This work is intended to provide a thorough derivation of all the relative constituent relations between the critical characteristics of the gun such as the strength of the forces acting on the rail and projectile, rail current, and initial velocity of the projectile. This makes it easier to identify what influences acceleration of the projectile, how much bracing each rail needs, how much initial velocity to give the projectile, etc. Design options discussed besides the standard design include the augmented rail system, a magnetic shell design, and a “wrap around” design. The tradeoffs encountered in each design are discussed in length. Due to the lack of a sufficient power source during testing the projectile was unable to travel down the length of the rails due to metal binding, insufficient pulse duration, and too much circuit resistance. It was found that using copper tungsten for the rails ensures that the rails can withstand the arcing inflicted by the kilo-Ampere current along the rails very well compared to other materials. Also, the copper in the tungsten alloy ensures high conductivity while the tungsten provides structural integrity to the rails during arcing between them and the projectile. Frequency response of conductive projectiles is characterized and improvements such as laminated projectiles are suggested as solutions to mitigate eddy currents induced in the projectile and improve performance.

Abstract:
Hydropower maintains its position as the most important source of renewable electric energy in the world. The efficiency of large hydropower plants is unsurpassed, and after more than hundred years of development, the technology is mature and highly reliable. While new hydro resources are currently being developed in Asia and South America, most European countries go through a phase of intense refurbishment and upgrading of existing plants. Challenges faced by the hydropower industry include a knowledge transfer to new generations and the adaptation of unit designs to meet new operational requirements. As with all branches of engineering, the use of computerized design tools has revolutionized the art of hydropower plant design and the analysis of its performance. In the present work, modern tools like coupled field-circuit models and semi-analytic permeance models are used to address different aspects of electromagnetic analysis of generators in large hydropower plants. The results include the presentation of a mathematical model that uses concepts from rotating field theory to determine the air-gap flux density waveform in a hydroelectric generator. The model was succesfully used to evaluate armature voltage harmonics and damper bar currents at no-load and load conditions. A second study is concerned with the importance of losses due to rotational fields in core loss calculations. It is found that dynamic and rotational effects typically increase the total core loss estimates with about 28% in large hydroelectric generators. In a third study, linear models for the calculation of salient pole shoe form factors at an arbitrary level of magnetic loading are presented. The effect of the damper winding configuration on the damping capability of salient-pole generators is then evaluated in a separate study. The predicted impact of the coupling between damper cages on adjacent poles on the damping torque production is verified in a set of experiments.

Abstract:
In this paper a moderate technique has been developed to improve an electromagnetic actuation principle for pumping systems, thus obtaining pulsating flow. This work consists of two parts, namely, a numerical part, in which ANSYS software is adopted to simulate the pumping process, while the experimental part consists of the fabrication and testing of the computer controlled electromagnetic pumping system. The objective of this work is to enhance both flow rate and outlet pressure. This was achieved via two main parameters, namely, the electromagnetic pulse duration and the width of each electromagnet. Results show that flow rate and outlet pressure increase with decreasing the pulse duration and with increasing each electromagnet width.

Abstract:
A new kind of electromagnetic valve [1], with great flow and fast speed, used in the medium pressure common rail electronically controlled fuel injection system of diesel engine is introduced for the first time. It is a kind of Two-position, Three-way Valve (TTV) that consists of a valve body, an outer valve rod and two inner valve rods. The electromagnet can generate great electromagnetic force because of its assembled magnetic fields. It actuates the outer valve rod from its closed-position to the open-position rapidly. A spring is used to push it back. Fuel injection begins when the outer rod is in the open position and ends in the closed. The inner and outer valve rods with taper valve port replace the traditional configuration and decrease the difficulties in machining. Finite element method has been used to analyze the electromagnet’s electromagnetic fields. Static characteristics of the electromagnet are calculated. Some factors such as working area, coil turns, core number, armature depth and iron material that influence the magnetic force are discussed in detail. The magnetic material and the electromagnet dimensions are optimized according to calculation results. Meanwhile, the leakage between the valve body and the outer valve rod, the leakage between the outer valve rod and left-inner valve rod and the leakage between the outer valve rod and the right-inner valve rod are also studied by the finite element method. Key part that causes the leak during operation has been found out and improvement is carried out. Influences of the TTV to the injection timing and the injection amount are analyzed in detail based on the Fuel Injection Test Platform (FITP) in the end.

Abstract:
Analytic techniques describing the electromagnet behavior, even of simple straight fibers of finite conductivity, have been developed only recently. The electromagnetic modeling of fiber-like particles formed (for example) in the process of burning hydrocarbons, i.e. soot, is very difficult. Although several analytic and numeric techniques are available, good experimental analogs have been lacking and the few that do exist are restricted to scattering only.

Full text
Abstract:
In this paper, the development of a novel electromechanical brake is presented for automotive applications. The proposed brake consists of multiple rotating disks immersed into a magnetorheological (MR) fluid, and an enclosed electromagnet. When current is applied to the electromagnet, the MR fluid solidifies as its yield stress varies as a function of the magnetic field applied by the electromagnet. This controllable yield stress produces shear friction on the rotating disks, generating the braking torque. An electromagnetic finite element analysis was performed to optimize the magnetic circuit within the MR brake and obtain its design parameters. With these parameters, a prototype MR brake was built; and the experimental results were compared to the finite element simulation results.

Abstract:
Eddy current dampers are promising devices for the passive and semi-active vibration control of mechanical structures. Among them “motional” eddy current dampers are based on the Lorentz forces between a moving conductor and a stationary magnetic field. “Transformer” eddy current dampers are based on the forces that develop in a voltage driven electromagnet when part of the magnetic circuit is movable. Considering the simplicity of the layout, transformer configurations seem to be very promising as alternative to traditional rubber or squeeze film dampers to control the lateral vibration of rotating machines. The aim of the present paper is to investigate the dynamic behavior of “transformer” eddy current dampers integrated in a mechanical structure. To this end the bond graph formalism is adopted with the aim of evidencing the causality effects between the mechanical and electromagnetic parts. The modeling approach allows to propose a design procedure of the damper. The mathematical models have been validated experimentally using two test benches with different layouts and geometrical characteristics of the magnetic circuit.

Abstract:
Explosion will generate electromagnetic radiation, the time domain waveform and spectrum generated from different types of explosives are different. For researching the characteristics of the electromagnetic radiation in process of explosion, the electromagnetic radiation signals and the images of the explosion process of typical single-compound explosives TNT and RDX are measured by wide band electromagnetic radiation signal measuring devices and high-speed photography. The experimental results show that the peak time of electromagnetic signals of TNT and RDX are significantly delayed compared with the initiation time of the detonation. The delay time of the peak signal of TNT explosion electromagnetic radiation is 55.07μs, and the delay time of RDX is 68.40μs. At 5m from the detonation center, the peak signal electric field strength of TNT and RDX explosion electromagnetic radiation is 1.92V/m. After the initial discharge interference signals have been removed, the electromagnetic pulse signals are analyzed by Fast Fourier Transform, it is shown that during explosion, the frequency of electromagnetic radiation is within 100MHz, and the frequency spectrums of electromagnetic radiation signals of different explosives are different.
