Description
Summary:This paper analyzes a set of first order triangular patch basis functions for the method of moments (MoM) solution of electromagnetic scattering problems, and compares its performance to the traditional Rao-Wilton-Glisson (RWG) basis. These basis functions provide a faster convergence and a smoother surface current representation. It is shown that the computational complexity involved is about the same as the RWG basis, which means that existing computer codes can be adapted to use them with minimal modifications.
