Computational electromagnetic (CEM) simulations have become an indispensable tool in analyzing and designing modern electromagnetic system. However, many challenges arise when applying CEM solvers to real world problems. Multiscale phenomena are one of them. The existence of both wave and circuit physics in such problems introduces large and small eigenvalues simultaneously that causes the resulting...
A domain decomposition scheme based on the equivalence principle, similar to Huygens' principle, for integral equation solvers and the method of moments is introduced. The equivalence principle allows the replacement of unknown currents distributed in a volume in space by equivalence currents residing on the surface that bounds the volume. It also allows the dissociation of the solution of one region...
In this paper, a domain decomposition scheme based on the equivalence theorem and the method of moments (MOM) is introduced. The unknowns on every subscatterer are transferred to the unknowns on its surrounding equivalent surface. With this scheme, both the number of unknowns and the memory usage are reduced
