Electromagnetic Waves in Chiral Media with Compensated Anisotropy

Abstract

We consider and compare three different cases of anisotropy compensation in chiral media. The first case concerns natural crystals or nonmagnetic superlattices, the second case is the class of stratified-periodic structures, which are homogeneous media in the long-wave approximation and have simultaneously dielectric and magnetic properties. The third possible case can be realized as inhomogeneous structures with spiral anisotropy of dielectric and magnetic properties.
