Reflection and Transmission of Electromagnetic Waves by a Moving Uniaxially Anisotropic Medium

Abstract

The problem of reflection and transmission of electromagnetic waves at the interface between a stationary isotropic medium and a uniaxially anisotropic medium moving parallel to the interface is investigated. Solutions are obtained for both incident E-wave and H-wave when the moving medium is either a non-dispersive uniaxial crystal or a dispersive uniaxial plasma. It is found that (i) total reflection is possible even if the wave is incident from a comparatively less ``dense'' medium into a ``dense'' medium; (ii) Brewster angles may exist even for incident E-wave; (iii) backward wave may be excited in the moving uniaxial plasma by an incident H-wave. Other interesting features which are not found in the case of two stationary media are also discussed in detail, and a few numerical examples are given.
