Abstract

A new method for obtaining mode cutoffs for asymmetric planar waveguides is developed. The method is based on defining the wave equation for modes at cutoff and solving it using the Galerkin method. The method has been used to obtain cutoffs of a variety of asymmetric waveguides with arbitrary profiles including exponential, traingular, parabolic and other power law profiles. Comparisons with available results show that very good accuracies can be obtained with moderate matrix sizes.
