摘要
A general fully coupled multi-hybrid method in three dimensions combining the finite element method, the method of moments, and a high-frequency asymptotic technique, namely, physical optics, is presented. Complex radiating structures are analyzed with finite element method (which easily handles complex geometries, permeable materials, anisotropy, and so on), while small- and medium-sized perfect electric conductor objects are rigorously analyzed using the method of moments; large perfect electric conductor objects can be efficiently analyzed with physical optics. Furthermore, different regions of the same object can be modeled with the method of moments and physical optics. Several numerical results are presented showing the validity of the method.
