Electromagnetic Waves in Anisotropic Dielectric Slabs.

Abstract

The theory of electromagnetic wave modes in an infinite anisotropic dielectric slab is reviewed. The theory is specialized to lithium niobate cut with its z-axis in the plane of the slab. It is shown that pure transverse electric (TE) and transverse magnetic (TM) modes propagate along the principal axes of the dielectric, but that coupled TE- and TM-like modes result for propagation at small angles with respect to these axes. The lowest order modes--the fundamental TE(0) and TM(0) modes--are determined, and the associated fields are plotted. One higher order mode--the TM(2)-like mode propagating at an angle of 19 deg with respect to one of the principal axes--also is plotted. These results relate to the problem of the interaction of sheet laser beams with surface acoustic waves. (Author)
