Abstract:
Abstract The spectral energy density of the internal waves in the open ocean is considered. The Garrett and Munk spectrum and the resonant kinetic equation are used as the main tools of the study. Evaluations of a resonant kinetic equation that suggest the slow time evolution of the Garrett and Munk spectrum is not in fact slow are reported. Instead, nonlinear transfers lead to evolution time scales that are smaller than one wave period at high vertical wavenumber. Such values of the transfer rates are inconsistent with the viewpoint expressed in papers by C. H. McComas and P. Müller, and by P. Müller et al., which regards the Garrett and Munk spectrum as an approximate stationary state of the resonant kinetic equation. It also puts the self-consistency of a resonant kinetic equation at a serious risk. The possible reasons for and resolutions of this paradox are explored. Inclusion of near-resonant interactions decreases the rate at which the spectrum evolves. Consequently, this inclusion shows a tendency of improving of self-consistency of the kinetic equation approach.

Abstract:
Nonlinear triadic interactions are at the heart of our understanding of turbulence. In flows where waves are present, modes must not only be in a triad to interact, but their frequencies must also satisfy an extra condition: the interactions that dominate the energy transfer are expected to be resonant. We derive equations that allow direct measurement of the actual degree of resonance of each triad in a turbulent flow. We then apply the method to the case of rotating turbulence, where eddies coexist with inertial waves. We show that for a range of wavenumbers, resonant and near-resonant triads are dominant, the latter allowing a transfer of net energy towards two-dimensional modes that would be inaccessible otherwise. The results are in good agreement with approximations often done in theories of rotating turbulence, and with the mechanism of parametric instability proposed to explain the development of anisotropy in such flows. We also observe that, at least for the moderate Rossby numbers studied here, marginally near-resonant and non-resonant triads play a non-negligible role in the coupling of modes.

Abstract:
Abstract. Nonlinear interactions of gravity waves are studied with a two-dimensional, fully nonlinear model. The energy exchanges among resonant and near-resonant triads are examined in order to understand the spectral energy transfer through interactions. The results show that in both resonant and near-resonant interactions, the energy exchange between two high frequency waves is strong, but the energy transfer from large to small vertical scale waves is rather weak. This suggests that the energy cascade toward large vertical wavenumbers through nonlinear interaction is inefficient, which is different from the rapid turbulence cascade. Because of considerable energy exchange, nonlinear interactions can effectively spread high frequency spectrum, and play a significant role in limiting wave amplitude growth and transferring energy into higher altitudes. In resonant interaction, the interacting waves obey the resonant matching conditions, and resonant excitation is reversible, while near-resonant excitation is not so. Although near-resonant interaction shows the complexity of match relation, numerical experiments show an interesting result that when sum and difference near-resonant interactions occur between high and low frequency waves, the wave vectors tend to approximately match in horizontal direction, and the frequency of the excited waves is also close to the matching value.

Oscillations of a tank at a near-resonant frequency have been shown to produce a response which changes from a ‘hard-spring’ to a ‘soft-spring’ response as the depth passes through a critical value. This paper investigates the transition region and it is shown, using a symbolic manipulator, that in fact the large-amplitude response is that of a soft spring on either side of this critical depth.

Abstract:
We consider the quantum mechanics of a model system in which meta-stable states arise through perturbation of a sequence of embedded simple eigenvalues with an embedded accumulation point. It is shown that the embedded eigenvalues become resonances in the perturbed system. These resonances also accumulate, and the position of the accumulation point is unchanged. The positions of the resonances are estimated uniformly up to the accumulation point. The meta-stable states associated with these resonances have the usual approximately exponential decay with time. Some applications to physical models are discussed.

Abstract:
Two compact planar crossed-dipole antennas loaded with near-field resonant parasitic (NFRP) elements are reported. The NFRP and crossed-dipole elements are designed for the desired circularly polarized (CP) radiation. By placing the NFRP element over the driven element at angles of 0 degrees and 45 degrees, respectively, dual-band and broadband CP antennas are realized. All radiating elements of antennas are 35 mm x 35 mm x 0.508 mm (0.187 lambda(0) x 0.187 lambda(0) x 0.0027 lambda(0) at 1.6 GHz) in size. The dual-band CP antenna has a measured vertical bar S-11 vertical bar < -10-dB bandwidth of 226 MHz (1.473-1.699 GHz) and measured 3-dB axial ratio (AR) bandwidths of 12 MHz (1.530-1.542 GHz) and 35 MHz (1.580-1.615 GHz) with minimum AR CP frequencies of 1.535 GHz (AR = 0.26 dB) and 1.595 GHz (AR = 2.08 dB), respectively. The broadband CP antenna has a measured vertical bar S-11 vertical bar< -10-dB bandwidth of 218 MHz (1.491-1.709 GHz) and a 3-dB AR bandwidth of 145 MHz (1.490-1.635 GHz). These compact antennas yield bidirectional electromagnetic fields with high radiation efficiency across their operational bandwidths.

Abstract:
Compared with the detector devices made of inorganic semiconductors, organic photodetectors are granted with additional strengths, such as flexibility, high scalability and bio-compatibility. However, in the family of organic optoelectronic devices, the detectors that are capable of detecting photons at two or multiple specific wavelengths are still missing. Such photodetectors are highly interesting because they could identify the target objects or materials much more precisely by detecting the reflected, transmitted or emitted photons at two or multiple characteristic wavelengths. In this thesis project, the optical simulations using Transfer Matrix Method (TMM) were performed on the organic devices to achieve the dual wavelength narrowband detection in the near-infrared (NIR) spectral range of 700 ~ 1100 nm. The devices use the fact that, at the interface of the blended organic electron donating and accepting materials, the charge-transfer (CT) states with the transition energies that are lower than the optical gap of the neat materials are formed. Combined with a Fabry-Perot resonant cavity, the CT absorption can be dramatically enhanced at certain wavelengths. The simulation results show that the two detection wavelengths can be tuned independently from 650 to 1100 nm. The spectral resolution (full with at half maximum - FWHM) of the detection bands varies between 10 and 30 nm. The simulated external quantum efficiency (EQE) is ~35% at 700 nm and ~10% at 1000 nm, respectively. A possible application of such photodetectors is for example moisture detection, where two of the characteristic absorption peaks of water are located at around 750 and 960 nm. By optimizing the thickness of the two photo-absorbing layers in a tandem device structure, the detection bands can be tuned to match with those two wavelengths for simultaneous and precise detection.

Abstract:
Plasmon resonance associated with nanoparticles of gold can enable photothermal ablation of tissues or controlled drug release with exquisite temporal and spatial control. These technologies may support many applications of precision medicine. However, clinical implementations of these technologies will require new methods of intraoperative imaging and guidance. Near-infrared laser surgery is a prime example that relies on improved image guidance. Here we set forth applications of augmented microscopy in guiding surgical procedures employing plasmon resonant gold-coated liposomes. Absorption of near-infrared laser light is the first step in activation of various diagnostic and therapeutic functions of these novel functional nanoparticles. Therefore, we demonstrate examples of near-infrared visualization of the laser beam and gold-coated liposomes. The augmented microscope proves to be a promisingimage guidance platform for a range of image-guided medical procedures.

Abstract:
While double negative (DNG) metamaterials (MTMs) were proposed over forty years ago, they have been experimentally demonstrated only in the last decade. The adaptation of a variety of epsilon-negative (ENG), mu-negative (MNG), and double negative (DNG) metamaterials, as well as single ENG, MNG,and DNG MTM unit cells, to achieve antenna systems exhibiting enhanced performance characteristics has received considerable research attention. These include, for example, electrically small antennas, multi-functional antennas, leaky-wave antenna arrays, and higher directivity antennas. Inspired by these metamaterial concepts, several metamaterial-engineered antennas have been investigated in this dissertation to achieve additional enhanced performance characteristics. First, several fabricated and tested variations of the three dimensional (3D) magnetic EZ (easy) antenna at 300 MHz and 100 MHz were examined. The 3D magnetic EZ antenna is composed of an electrically small loop antenna that is coaxially-fed through a finite ground plane and that is integrated with an extruded capacitively loaded loop (CLL) element. This 3D CLL structure is designed to be a near-field resonant parasitic (NFRP) element. With the proper placement of the NFRP element in the very near field of the driven element, it was demonstrated that the overall antenna system achieved complete matching to the source without any external matching network, along with an enhancement of the overall radiation efficiency. Additionally, multi-functional 3D magnetic EZ antennas were designed for wireless communication applications. For instance, by incorporating multiple NFRP elements, several dual-band versions were realized. Second, by properly combining and phasing their effective magnetic dipoles, electrically small multi-band, circular polarized (CP), metamaterial-inspired wire antennas were perfected that are nearly completely matched to a 50 Ω source and have high radiation efficiencies. Again, they were accomplished by incorporating multiple NFRP elements into their designs. Finally, two tri-band-notched UWB antennas were developed and tested successfully. The notched filters were achieved by introducing printed, electrically small CLL resonators into the UWB antenna design. Each CLL element has a high-Q characteristic and a compact size, which made it a very suitable candidate for a band-stop filter function. Like the split ring resonator (SRR) element, the CLL element is self-resonant and has a resonance frequency that is determined primarily by its loop inductance and the capacitances resulting from the cuts which opened the loop. In contrast, the CLL element has a much simpler, more compact design. It was demonstrated that by placing one, two or three CLL elements near the feedline of the UWB antenna and by tuning their sizes, one can control the band-notched frequencies of the radiator, while minimizing their space requirements, to achieve single, dual, and tri-band notched-filter UWB antennas.

Abstract:
Metamaterials have drawn considerable attention because they can exhibit epsilon-negative (ENG) and/or mu-negative (MNG) properties, which in turn can lead to exotic physical effects that can enable interesting, practical applications. For instance, ENG and MNG properties can be engineered to yield double negative (DNG) properties, such as a negative index of refraction, which leads to flat lenses. Similarly, their extreme versions enable cloaking effects. Inspired by such metamaterial properties, a promising methodology has been developed to design electrically small antennas (ESAs). These ESAs use unit cells of metamaterials as their near-field resonant parasitic (NFRP) elements. This new metamaterial-inspired antenna miniaturization method is extended in this dissertation by augmenting the antenna designs with circuits. A rectifying circuit augmentation is used to achieve electrically small, high efficiency rectenna systems. Rectennas are the enabling components of power harvesting and wireless power transmission systems. Electrically small, integrated rectennas have become popular and in demand for several wireless applications including sensor networks and bio-implanted devices. Four global positioning system (GPS) L1 frequency (1.5754 GHz) rectenna systems were designed, fabricated and measured: three resistor-loaded and one supercapacitor-loaded. The simulated and measured results will be described; good agreement between them was obtained. The NFRP ESAs are also augmented with active, non-Foster elements in order to overcome the physical limits of the impedance bandwidth of passive ESA systems. Unlike conventional active external matching network approaches, the non-Foster components are incorporated directly into the NFRP element of the ESA. Three 300 MHz non-Foster circuit-augmented broadband, ESA systems were demonstrated: an Egyptian axe monopole (EAM) antenna, an Egyptian axe dipole (EAD) antenna, and a protractor antenna. The simulated and measured results will be described; reasonable agreement between them was obtained. Moreover, a deeper practical engineering understanding of how lumped components with tighter tolerances, more accurate transistor models, and integrated circuit-based implementations will lead to more satisfactory performance characteristics of the non-Foster circuit-augmented ESAs was accomplished and is also reported.

Abstract:
A pattern-reconfigurable, low-profile, efficient, electrically small, near-field resonant parasitic (NFRP), Huygens source antenna is presented. The design incorporates both electric and magnetic NFRP elements. The electric ones are made reconfigurable by the inclusion of a set of p-i-n diodes. By arranging these electric and magnetic NFRP elements properly, a set of three Huygens sources are attained, each covering a 120 degrees sector. Pattern reconfigurability is obtained by switching the diodes on or off; it encompasses the entire 360 degrees azimuth range. A prototype was fabricated and tested. The numerical and experimental studies are in good agreement. The experimental results indicate that in each of its instantaneous states at f(0) = 1.564 GHz, the antenna provides uniform peak realized gains, front-toback ratios, and radiation efficiencies, respectively, as high as 3.55 dBi, 17.5 dB, and 84.9%, even though it is electrically small: ka = 0.92, and low profile: 0.05 lambda(0).

Cette thèse présente une étude expérimentale des modifications des propriétés de diffusion résonante de la lumière par des nuages mésoscopiques de rubidium 87 froids dont la densité peut être variée. pour des densités de l’ordre de 1014 atomes/cm3, les distances entre certains atomes deviennent bien plus petites que la longueur d’onde du rayonnement à résonance avec la transition d2 (780 nm) du rubidium 87. l’ampleur des interactions dipôle-dipôle entre ces diffuseurs empêche alors de les considérer comme étant indépendants les uns des autres: on parle de diffusion collective. les méthodes employées pour produire les échantillons étudiés s’appuient sur des techniques de refroidissement (ralentisseur zeeman et piège magnéto-optique) et de piégeage (pinces optiques) d’atomes neutres permettant d’obtenir des ensembles d’atomes froids (environ 100 µK) allant d’exactement un à plusieurs centaines d’entre eux. les observations réalisées portent sur la lumière diffusée par ces atomes, collectée grâce à un système optique de grande ouverture numérique. l’étude consiste dans un premier temps en la caractérisation la diffusion résonante de lumière par un unique atome. elle aboutit notamment à la mesure du retard dans la diffusion par un atome d’un paquet d’ondes lumineuses, appelé délai de wigner, dans des conditions proches d’une expérience de pensée. dans un second temps, cette étude porte sur les propriétés de diffusion collective de lumière par des ensembles denses d’atomes. elle rapporte en particuliers une mesure de la suppression de l’excitation des nano-nuages en fonction de leur densité
This thesis reports an experimental study of the modifications of the near-resonant light scattering properties of mesoscopic cold clouds of rubidium 87 which densities are tunable. for densities of the order of 1014 atoms/cm3, inter-atomic distances can be smaller than the wavelength of the radiation at resonance with the d2 line (780 nm) of rubidium 87. the magnitude of the dipole-dipole interactions between the scatters is such that they can no longer be considered as independent of each other: a phenomenon called collective scattering. the methods used to produce the studied samples are based on cooling (zeeman slower and magneto-optical trap) and trapping (optical tweezers) techniques for neutral atoms. they allow obtaining cold (100 µK) atomic ensembles containing from exactly one to several hundreds of atoms. the observations performed are based on the light scattered by these atoms which is collected thanks to a high numerical aperture optical system. in a first step, this study consists in characterizing the near-resonant light scattering by a single atom. it leads to the measurement of the delay in the scattering by an atom of a wave packet of light, called wigner delay, in conditions close to those of a gedanken experiment. in a second step, this study deals with the collective scattering of light by dense atomic ensembles. it especially reports a measurement of the suppression of the excitation of the nano-clouds versus their densities

Abstract:
This chapter introduces the reader to canonical perturbation theory as a tool for studying near-integrable systems. Many problems in physics and chemistry do not have exact analytical solutions; these systems are in direct opposition to integrable systems and action-angle variables. The chapter starts by considering tiny perturbations to integrable Hamiltonians. Poincaré in 1893 claimed this was the fundamental question of classical mechanics and, fittingly, Hamilton–Jacobi theory is the starting point. The chapter develops Poincaré’s fundamental equation as well as Delaunay’s small divisor problem. Resonant, near–resonant and non-resonant tori are investigated in the context of Poincaré’s theorem and KAM theory is described in detail. Chaos and Poincaré maps are presented before discussing determinism, deterministic chaos and Laplace’s demon.

Abstract:
Abstract Remediation of water from tailings is a critical and challenging issue in many industries, particularly in oil sand refineries and waste water treatment. Mining of the Canadian oil sands, also one of the largest known crude petroleum reserve in the world, is done to extract bitumen by the processes like hot water extraction, resulting in numerous amounts of tailings (large ponds). Techniques that can achieve contaminant separation over large surface areas/volumes, with low energy input, and at a low economic investment are of primary interest. Hence, such techniques can be applied for the manufacturing industries with the similar concerns. In this paper, a di-electric heating method is presented that combines electrical standing wave voltage amplification with porous interface (carbon foam) materials to intensify water evaporation. The system targets the di-electric loss tangent of the aqueous solution accompanied with porous interface by operating at a high voltage and frequency in the low megahertz (1–5 MHz). The non-uniform charge distributions across the interface material enables distributed heat localization at the air-water/material boundary, therefore avoiding bulk heating. The most important parameters determining efficiency of capacitive heating are determining the resonant frequency of material in contact with the heating end of helix, and properties of the interface material. Different porous configurations treated for the application were applied as interface layers and the experimental results demonstrate an 80% increase in evaporation rates compared to solar and natural heating. The combination of electrical heating with reduced heat losses results in accelerated vapor generation. Hence, results showcase heat localization at the interface, electric field at the heating boundary and energy requirements for the mentioned scenario. The proposed method offers a promising solution to localize heat over a large area by application of low-cost porous materials and high voltage/high frequency electrical resonators for use in water treatment, remediation, and go further with distillation applications for water reclamation.
