Abstract:

 An overlapped domain decomposition method with congruent sub-domains is proposed for solving
electromagnetic surface integral equations. Based on congruent sub-domains, the proposed method creates a
set of uniform mesh such that all the self-matrixes on the congruent sub-domains share an interior-interior
sub-matrix. The method can significantly reduce the memory requirement and the matrix filling time. It
can produce results consistent with those obtained with the MoM and the overlapped domain decomposition
method, while reduce the memory requirement and the CPU time. That is shown in the computation examples
presented in the paper, indicating correctness and effectiveness of the proposed method.

Key words: surface integral equation, electromagnetic scattering, overlapped domain decomposition, congruent sub-domain
