Abstract
Using the electromagnetic wave method and Huygens’ principle, we have studied light refraction and reflection on the boundary between two uniaxial crystals with arbitrary optic axis orientations. We provide a set of direct formulas that calculate the directions of the refracted and reflected extraordinary rays and their associated waves, as well as the ray indices and refractive indices. The formulas use only the initial input variables and do not require the calculation of intermediate quantities. Refraction and reflection are combined in one formula. We also prove that the electromagnetic wave method and Huygens’ principle produce analytically equivalent results for geometrical ray tracing.
