Texte intégralThe present thesis work relates to transformational optics and its applications. Invisibility cloaks and carpets, as well as mimetic coatings, are studied using simulations with the commercial software COMSOL Multiphysics in the micro-wave domain. First, these simulations help in the understanding of the phenomena at stake and allow us to evaluate how challenging it would be to develop experimental devices. Based on objective criteria, we consider multiple systems and discuss their efficiency and feasibility. The realization of transformation optics coatings is a difficult challenge, so we suggest a multilayer design for the coatings. As dielectric permittivity and magnetic permeability required in the OT coatings are unusual among natural materials, we worked on resonant metamaterials composed of a lattice of small conducting structures. The physical origin of the phenomenon is investigated, as the homogenization technics allowing computation of effective homogeneous parameters. Finally, we consider the realization of invisibility cloaks using frequency dispersive metamaterials and developed a design allowing broadband operations

Texte intégralThis phD work is an original and important contribution to the understanding of transformation optics and paves the way to the design of new electromagnetic structures. The coupling between this innovative technique and metamaterials has led to prototypes with unique properties. We have thus developed an invisibility polygonal cloak, an electromagnetic taper, a directional antenna and isotropic source. The realization of our high-directive antenna with this method is the only prototype in the literature that combines controlled variations of the permittivity and permeability from electric and magnetic resonators. The ultimate control of light from an engineering space will find its usefulness in fundamental research but also for engineers and developers who are looking for more precision in the design of electromagnetic devices

Invisibilidade sempre mexeu com a imaginação de crianças e adultos. Quem nunca imaginou ser capaz de tornar-se invisível em certas ocasiões? Recentemente essa ideia da ficção científica tomou forma na vida real, e um dos objetivos do presente texto é explicar de uma maneira acessível as principais ideias físicas e matemáticas por trás do conceito de invisibilidade. Pedimos do leitor somente uma modesta familiaridade com Cálculo Vetorial, Séries de Fourier e Álgebra Linear. O objetivo da capa de invisibilidade é tornar um objeto não detectável por meio de energia eletromagnética. A capa é fisicamente realizada por um metamaterial especialmente projetado para redirecionar certas ondas eletromagnéticas irradiadas sobre o objeto. Nesta exposição, usaremos como exemplo a tomografia de impedância elétrica (TIE) como método de detecção e explicaremos como criar uma capa invisível à TIE. Cabe ressaltar que o processamento de imagem através da TIE diz respeito a um problema inverso e, no contexto das equações diferenciais, esse problema envolve, a partir de determinadas simplificações, a equação de Laplace com condições de contorno. Despretensiosamente, optamos pelo caso bidimensional para facilitar a exposição das idéias principais, embora todos os nossos resultados possam ser generalizados em 3 dimensões.
Invisibility has always instigated children and adult s imagination. Who never thought of occasionally being able to turn yourself invisible? Recently, this science fiction idea has taken shape in real life, and one of the objectives of this text is explain the main physical and mathematical ideas behind the invisibility concept, on a comprehensible way. We only require the reader has a modest familiarity with Vectorial Calculus, Fourier Series and Linear Algebra. Invisibility cloak aims to turn an object imperceptible to electromagnetic energy detection. The cloak is made of an especially projected metamaterial that redirects certain electromagnetic waves irradiated over the object. Here we will take as an example electrical impedance tomography (EIT) as a detection method and we will explain how to create an invisible cloak for EIT. It is worth mentioning that image processing through EIT is an inverse problem. Thereby, in the context of differential equations, this problem involves a few simplifications in the Laplace s problem with contours conditions. Unpretentiously, we chose the two-dimensional case to simplify the exposition of the main ideas, although all of our results may be generalized in three-dimensional case.
