Nonradiative surface electromagnetic waves at the interface of uniaxially bianisotropic enantiomeric media

摘要

A new class of nonradiative surface electromagnetic waves guided by the interface between two enantiomorph uniaxially bianisotropic media is predicted. The waves are caused by bianisotropy and are absent in the case of enantiomorph bi-isotropic materials. The basic properties of the waves, in particular, dispersion relation and localization conditions differ dramatically from those for conventional surface waves propagating along the interface between chiral and achiral media, as well as between two different achiral media. These waves can be considered as a generalization of Dyakonovtype surface waves in the case of enantiomeric bianisotropic media.
