The linearly polarized incident wave is distorted after transmission through the sample and transformed into left-handed elliptically polarized.

Electromagnetic metamaterials present exotic and unusual properties hardly to be found in nature with many potential applications. They are usually built by distributing small resonant structures in periodical lattices. If the structure has chiral symmetry, the medium is called chiral metamaterial. Here the electrodynamics behavior of a chiral structure with a huge electromagnetic activity at microwave frequencies is modeled by making use of COMSOL Multiphysics RF's Module and successfully compared to the experiment. Linearly and circularly polarized modes at normal incidence have been simulated and different experimental conditions have been modeled to extract reflection and transmission coefficients for the electromagnetic characterization of the sample.
