Extraordinary-ray and -wave tracing in uniaxial crystals.
Solutions for tracing the extraordinary ray through a uniaxial nonabsorbing birefringent crystal are presented in a simple and explicit form that is directly amenable for computer programming. The general case in which the incident ray, the optic axis, and the exit surface have arbitrary orientation with respect to the entrance surface is treated. Solutions for the extraordinary wave vector within the crystal are also given.
