Abstract

The two governing equations for the evanescent wave excitation of planar dielectric waveguides are deduced by a quasi-optical technique. These governing equations, which are in a canonical form that is appropriate for any coupler with a guided mode and a radiated wave, satisfy reciprocity and power-conservation requirements.
