Etude des metamateriaux et leurs applications dans les systèmes micro-ondes

Abstract

Metamaterials are gaining momentum in recent years. The new properties allow to consider the development of new electronic components for new applications. The use of these materials offers advantages such as reducing weight and bulk, which is beneficial for their integration into an electronic system. In this thesis, we are focused in the simulation of the microwaves metamaterial devices. Various components (antennas, biosensors) were designed, simulation was made using software HFSS. This work is structured around two major axes: The first axis deals with the design of me tamaterials inspired – antennas. The results obtained show a multifrequency comportment as well as obtaining radiation patterns of different shapes, which allows these structures to be good candidates for applications in wireless communication systems. The second axis presents metamaterial-based biosensor. Simplicity and speed of analysis are the main advantages of a biosensor
