Abstract

In the last few years a new class of materials, namely the metamaterials, have emerged in the scientific community. The use of these materials allow us to obtain unique electromagnetic properties not found in nature, such as negative refractive index. Nowadays, there exist many applications making use of these special properties in sensors, invisibility cloaks, and antennas, aiming at improving the performance of these structures. Based on these considerations, this project will focus on the design of metamaterial structures aiming at controlling the radiation properties of antennas in the microwave region, such as directivity and gain. It will be given emphasis on chiral metamaterials, mostly due to the phenomenon of electromagnetic field rotation. In addition, chiral metamaterials are a good alternative to obtaining media with zero or negative refractive index. This work also includes the design, modeling, and experimental characterization of these structures. This new technology has the potential to be applied both in terrestrial and space communications.
