Starting from equivalence theorem any composite metallic and dielectric structure can be analyzed by using SIE (Surface Integral Equation). Such integral equations are usually solved by MOM (Method Of Moments). Most of the existing MOM methods for solving SIE are developed for BORs (Bodies Of Revolution). There are only few such methods that can handle structure of arbitrary shape. These methods use sub-domain basis functions defined over the triangles, requiring very large number of unknowns even for simplest problems. Particularly, these methods can not model the multiple junction of metallic and/or dielectric edges and protrusion of wire through the dielectric surface. Hence, most problems of interest in practice can not be successfully analyzed by the existing methods.
