Abstract

A special type of surface wave was predicted by M. I. Dyakonov in 1988 [1]. Such waves exist under special conditions at the interface of transparent anisotropic materials, and hens they are lossless. This surface waves require at least one of the two media to be an anisotropic medium, either biaxial or positive uniaxial, and various configurations have been investigated [2]. In the case of the interface of a biaxial anisotropic medium with refractive indices n_x, n_y and n_z, and an isotropic medium with refractive indices n, surface waves form only when the refractive indices fulfill the condition
