PROPAGATING EIGENMODES FOR PLANE-WAVES IN A UNIAXIAL BIANISOTROPIC MEDIUM AND REFLECTION FROM A PLANAR INTERFACE

A time-harmonic electromagentic plane wave propagating in a uniaxial bianisotropic medium is considered. Forward- and backward-going eigenmodes are identified together with their dispersion equations. The eigenmodes consist of two pairs with different phase velocities and the two components of each pair correspond to forward- and backward-going modes. The propagating modes are then used to calculate the reflection coefficient matrix at an interface between a vacuum and a uniaxial bianisotropic half-space. Numerical results for such a reflection are presented as a function of the direction of the optical axis.
