Texte intégralThis thesis aims at highlighting recent advances in the field of metasurfaces. These structures have been used to improve the performances of conventional antennas or to design new antenna concepts. The work has been carried in the framework of a collaboration with industrial partners, namely Airbus Safran Launchers, Airbus Group Innovations and CNES. The manuscript is organized into two parts. The first part is devoted to metasurfaces used as partially reflecting surfaces (PRS) to design Fabry-Perot cavity antennas. In this part, an analytical model allowing to predict the beam steering angle by a phase modulation along the PRS is developed. Then, a new concept of metasurface allowing to steer the main antenna beam is proposed. It consists in applying a phase gradient by varying the effective index of the substrate that constitutes the PRS. The second part of this thesis is devoted to the design of an active metasurface that allows emulating different functionalities. First, the metasurface is utilized as a reflector with frequency and steering reconfigurability characteristics. Then, this metasurface is used as a reconfigurable polarizer where linearly polarized incident waves are converted into circularly polarized ones. Finally, the last study concerns the use of the active metasurface for the design of reconfigurablecylindro-parabolic and corner reflector antennas

Texte intégralMaterials are generally classified in terms of their constitutive parameters, the complex permittivity and permeability , in the frequency domain. These parameters are used to determine the response of materials to electromagnetic (EM) radiation. Materials found in nature have positive real parts for both and . In recent years, researchers have shown that a new class of materials called metamaterials (MTMs), characterized by inclusions of various shapes and materials that are small compared to wavelength, result in an effectively homogeneous medium with the unique properties of negative real and which cause EM waves traveling through the medium to exhibit unusual characteristics. Zero specular reflection layers for four material types such as double positive (DPS), double negative (DNG), epsilon-negative (ENG) and mu-negative (MNG) materials are examined in this thesis. For each defined type of MTM, the transcendental equations are derived and solved numerically to generate curves for zero specular reflection. A MATLAB program was developed to generate universal curves for DPS, DNG, ENG, and MNG materials. The results were discussed and evaluated to determine wave behavior in each type of MTM as well as how they can be used as a matched-surface radar-absorbing material (RAM) for military application. The results were compared to published data.

Texte intégralFor more than twenty years now, Acoustic Metamaterials are experiencing a growing success, partlydue to exotic phenomena and their wide variety of extremely promising applications: “InvisibilityCloak” is the most vivid example of this. In this thesis, we report on designs of locally resonantacoustic metamaterials, that enable us to generate both sound opacity and transparency. It is moreparticularly coupling between resonators having different forms which is the focus of our work.This study permit us to understand that diffraction is one of the main limitation of omnidirectionalcapabilities involving locally resonant perforated plates, as supported by experimental investigationsrealized using a motorized ultrasonic set-up. We proposed solutions to overcome such a limitation,in the case where the opacity mechanism uses diffraction gratings. From this, we transposed theresults obtained in ultrasonic frequencies to the audible range, which permits us to develop twomain kinds of acoustic devices based on metamaterials: broadband reflectors and low-frequencyabsorbers. Finally, homogenization study of such structures revealed an effect of density near-zero,with applications from shaping wave front, to acoustic furtiveness. Such results paves the way forpromising applications in various field, including construction, automotive and aeronautical industries,submarine acoustics and so on
Hammoud, Mohamad. « Etude et conception d'antennes imprimées sectorielles à faibles lobes arrière pour réseau Wi-Fi outdoor maillé ». Thesis, Montpellier, 2020. http://www.theses.fr/2020MONTS032.
Texte intégralIn the frame of outdoor meshed Wi-Fi network operating in the 2.4 GHz frequency band, we conceive sectoral antennas with very low front to back radiation ratio. This should limit co-channel interferences between neighboring base stations. We first study radiating elements in microstrip technology associated with a reflector based on metamaterials. The latter is based on the structure of Sievenpiper, the so-called "mushroom" structure. This structure comprises periodic pattern sprinted on a substrate. Simulations of the dispersion diagram and of the phase of the reflection coefficient, linked to numerous results from the literature, allow us to perform a full-through characterization of these reflectors. We can therefore propose a criterion on the geometry of the patterns bringing the high-impedance frequency band within the forbidden electromagnetic bandgap. The behavior of the overall antenna, radiant element and reflector, exhibits very interesting performances considering bandwidth and radiation lobes. For economic reasons, this structure is not retained and we switch to a simple perfect electric conductor plane. A part of this thesis explores the impact of printed antenna geometry and its associated reflector on the gain and front to back ratio characteristics. We finally choose a loop geometry. This work is achieved with 3D electromagnetic simulations and with outdoor measurements. On-field experiments on a prototype comprising 3 tri-sectoral antennas assembled under a Radome validate and concludes the study

Texte intégralMechanical microstructured metamaterials are increasingly gaining attention from the scientific and engineering community. The question of modeling the behavior of metamaterials is of extreme importance. Some choose an approach, which is reminiscent of the classical theory of elasticity: enriched continuum mechanics. We employ the enriched continuum model named relaxed micromorphic model in order to study wave propagation and scattering at interfaces between materials and metamaterials. Dealing with the correct boundary conditions at the macroscopic scale becomes challenging. We show how finite-domain boundary value problems can be set-up in the framework of the relaxed micromorphic model. We set up the full plane wave solution of the scattering from an interface separating a Cauchy medium from a relaxed micromorphic one. Both media are isotropic and semi-infinite. Generalized macroscopic boundary conditions are presented, which allow the effective description of the scattering properties of an interface between a homogeneous solid and a mechanical metamaterial. The associated generalized energy flux is introduced. We show that the contrast of the macroscopic stiffnesses of the two media, together with the type of boundary conditions strongly influence the onset of Stoneley waves at the interface. This allows to tailor the scattering properties of the interface at both low and high frequencies, ranging from zones of complete transmission to zones of zero transmission well beyond the band-gap. We then consider a bulk wave propagation problem and show that the transient waveforms arising from several localised pulses in a micro-structured material can be reproduced. We compare the dynamic response of a bounded micro-structured material to that of bounded continua with special kinematic properties. We show that, while the Cauchy theory is able to describe the overall behavior of the metastructure only at low frequencies, the relaxed micromorphic model goes far beyond by giving a correct description of the pulse propagation in the frequency bandgap and at frequencies intersecting the optical branches. Finally, we present the case of a metamaterial slab of finite width. Its scattering properties are studied via a semi-analytical solution of the relaxed micromorphic model and compared to numerical simulations encoding all details of the selected microstructure. The reflection coefficient obtained via the two methods is presented as a function of the frequency and the direction of propagation of the incident wave. We find excellent agreement for a large range of frequencies. The case of a semi-infinite metamaterial is also presented and is seen to be a reliable measure of the average behavior of the finite metastructure
