Abstract

The values of the propagation constants, which correspond to maxima of the real part of the functional derived from a variational principle, by using of the exact analytical eigenfunctions, are used as initial guesses to increase the efficiency for complex root searching of the associated dispersion equation for a multilayer planar waveguide. This variational method is used to study the effects of addition of a low-index buffer layer over a high substrate on the propagation characteristics of the waveguide..
