Reflection from an oriented biaxial surface.
Analytic expressions for the amplitude reflection and transmission coefficients for light incident on a biaxial anisotropic material are presented for the special case where one of the principal axes of the material is parallel to the surface of the material. It is assumed that either the material or the light source can be oriented so that the principal axis that is parallel to the surface is also perpendicular to the plane of incidence of the light.
