Abstract
The propagating electric fields in rectangular waveguides loaded by a homogeneous dielectric layer are evaluated using the ray-optical technique. The accuracy of the asymptotic solution is investigated and the results are shown to be in good agreement with the exact LSEmn-mode solution. It is concluded that, with this critical evaluation, more reliance can be placed on the accuracy of the method for other schemes for which no exact solutions are available for comparison.Keywords
