Arbitrary metallic and dielectric/magnetic structures can be analyzed by applying the method of moments (MoM) to the surface integral equations (SIEs). Such a structure is usually modeled by triangular or quadrilateral patches. Hierarchical higher order basis functions defined on those patches allow very efficient analysis. However, even for such sophisticated current expansions, the number of unknowns for electrically large structures can be so high that the analysis based on the direct… CONTINUE READING
