Abstract

A general fully coupled multi-hybrid method in three dimensions (3D) combining the Finite Element Method (FEM), the Method of Moments (MoM), and a high frequency asymptotic technique, Physical Optics (PO), is presented. Complex radiating structures are analyzed with FEM (which easily handles complex geometries, permeable materials, anisotropy, and so on) while small and medium size perfect electric conductor (PEC) objects are rigorously analyzed using MoM; large PEC objects can be efficiently analyzed with PO. Furthermore, different regions of the same object can be modeled with MoM and PO. That provides the possibility, for instance, of taking into account the edge effects of PEC objects without the need of introducing artificial line currents at the edges, as the Physical Theory of Diffraction (PTD) does. Several numerical results are presented showing the validity of the method.
