EIGENEQUATIONS AND COMPACT ALGORITHMS FOR BULK AND LAYERED ANISOTROPIC OPTICAL MEDIA - REFLECTION AND REFRACTION AT A CRYSTAL-CRYSTAL INTERFACE

Eigenequations leading to compact algorithms for computing the optical properties of anisotropic media that may be stratified in the x-direc tion are described. For each medium a 4 x 4 matrix (F) over cap of bas is field vectors is determined as the eigenvectors of a 4 x 4 matrix f orm of Fresnel's equation. A minimum sort of the columns of (F) over c ap that is necessary for a birefringent cover or substrate separates b asis vectors that carry power in the positive and negative x-direction s respectively. A sorting procedure is discussed for the most complica ted refractive index section in which the outer and inner sheets do no t touch and the outer sheet has a well defined cusp. MATLAB code is pr ovided for the implementation of basic routines. (C) 1997 Academic Pre ss.
