A Bianisotropic Left-handed Metamaterials Compose of S-ring Resonator

摘要

A realization of a kind of bianisotropic left-handed material based on the structure of S-ring resonator is proposed in this paper. By subtly shorting some horizontal metallic strips inside of the ring, magnetoeffectric coupling is raised, leading to a bianisotropic effect in this Artificial medium. The structure is theoretically analyzed from a microscopic viewpoint and its macroscopic constitutive parameters are presented, where a nonzero chirality component is shown. Due to the existence of the bianisotropy, we theoretically show the existence of cross polarization effects when wave incident onto a slab of this material, and numerical simulations on the real structure confirms the results predicted by our theoretical analysis.
