Abstract
The interaction of opposing TE-waves in a nonlinear cubical dielectric located in a waveguide of arbitrary cross-section is examined. It is shown that the propagation constants of the interacting waves are functions of the combination of the amplitudes of those waves. Wave reflection and refraction in a nonlinear plate are investigated. A formula for the reflection coefficient and a “trnasillumination” condition of the nonlinear plate are obtained.
