Extreme electromagnetic properties with bianisotropic nihility

Abstract

Bianisotropic media besides permittivity and permeability possess additional material parameters describing bianisotropic coupling. Here we consider the scenario when bianisotropic parameters are non-zero, while the permittivity and permeability tend to zero. Only a special case of reciprocal bianisotropic nihility was studied in the literature. In this work we generalize the concept of bianisotropic nihility to the case of non-reciprocal matter. We explore unique electromagnetic properties of bianisotropic nihility materials and consider their potential applications.
