A hybrid PO-MoM domain decomposition method based on equivalence theorem

This paper introduces a new PO-MoM hybrid method based on the equivalence principle for the object that can be decomposed into different isolated parts. Each part can be solved by MoM or PO according to its local property. The unknowns on every subscatterer are transferred to its surrounding equivalent surface with a new scheme, and the intersections between different parts are also considered by their equivalent surfaces. Numerical results demonstrate that the proposed method can achieve better efficiency and reasonable agreement with the results by the MoM.
