Abstract

In this paper CFIE formulation is presented to analyze broad wall slots of arbitrary shape partially filled with homogeneous dielectric materials. The ldquogeneralized network formulationrdquo for aperture problems is formulated in terms of linear operator equations and expanded in RWG functions in a Galerkin sense. The approach uses a simultaneous representation of the equivalent surface current densities. Representative aperture shapes have been considered such as rectangular, elliptic, and cross-shaped. Numerical results are presented, which are in good agreement with the published data.
