Towards New Low Loss Microwave Chiral Media Based on Dielectric Inclusions

Abstract

In the last years, the Research Groups on Computational Electromagnetics (GrECo), from the University of Valladolid, and on Applied Electromagnetics, from the University of Murcia, have been working together in the design, fabrication, modelling and measuring new chiral media to be used in the microwave frequency range. This has been done in the frame of Research Projects funded by Spanish Government and, as a result, chiral media based in metallic inclusions in a host dielectric have been performed. The latest realizations, until now, use metallic “crank-like” inclusions assembled in various geometries to avoid undesired effects such as anisotropy, non-reciprocity and polarization filter effects.
