Reflection of waves at planar interfaces associated with a uniaxial medium is theoretically analyzed by examining the boundary condition and the dispersion relation. Simple global expressions of incident and reflected angles of both wave vectors and ray vectors are derived. The relations between them are obtained. It is also shown that negative reflection can be realized in all uniaxial media under certain conditions. Our results offer considerable potential device applications of uniaxial media.
