INTERNAL-REFLECTION IN UNIAXIAL CRYSTALS .2. COEFFICIENTS OF TRANSMISSION AND REFLECTION FOR AN ORDINARY INCIDENT WAVE

The boundary condition at the interface between a crystal and an isotropic medium have been solved in a general form for the situation when an ordinary ray is incident from the crystal and gives rise to two reflected rays besides the refracted ray. With the formulae obtained, the reflection and transmission coefficients have been calculated as functions of the incidence angle, and a pseudo-Brewster angle was observed to exist for each one of the reflected rays. © 1990 Taylor & Francis Ltd.
