A domain decomposition method for analysis of electromagnetic scattering from cavities

A non-overlapping domain decomposition method is applied to solve surface integral equations for electromagnetic scattering from cavities. This scheme allows the cavity to be divided into sub-domains and can be solved in a serial or parallel manner. Thus, the memory requirement and CPU time for modeling cavity structures can be dramatically reduced. Moreover, the interior resonance problem is eliminated from this scheme, which occurs in the generalized network formulation.
