Pyramidal and Entire Domain Basis Functions in the Method of Moments

Abstract

New basis functions are used for the problem of solving the surface current on a conducting plate by the method of moments. Pyramidal functions adopted from the finite element method are geometrically flexible. Entire domain trigonometrical functions offer the advantage of computing the tangential electric field everywhere on the surface of the plate, because the surface charge densities are continuous. In this way the error can be estimated in the domain of the operator.
