Etude Et Simulation Des Caractéristiques Des Structures Périodiques Métallodiélectriques.

Résumé: This thesis work was devoted to the study and simulation of the characteristics of periodic metallo-dielectric structures. Our interest was to study periodic structures, more precisely, a one-dimensional multilayer periodic photonic crystal by proposing a new conception and analysis of these structures. We first recalled the new calcification of materials, basic concepts related to periodic structures including photonic crystals; their different types, their physical and geometrical properties, the notions of photonic bands as well as the methods of modeling periodic structures based on these materials. Then, in the second chapter, we presented a theoretical study of the transmission properties of one-dimensional multilayer periodic structure without defect containing alternating layers of positive and negative refractive index. Next, a selective filter based on the use of a one-dimensional multilayer periodic photonic crystal structure has been presented in the third chapter. We ended with the fourth chapter, where we proposed new design and analysis of a one-dimensional photonic crystal structure (1D-PC) based on the use of a single dielectric with the integration of the doping technique.
