In this paper, an efficient and accurate unified approach is proposed tosolve transverse magnetic scattering problems by multilayer embedded objects.In the proposed approach, an equivalent current density is derived when theequivalent theorem is recursively applied on each boundary from inner toexterior regions. Then, the objects are replaced by the background medium andthe equivalent electric current density enforced on the outermost boundaryremains fields in the exterior region unchanged. Therefore, the scatteringproblems by the multilayer embedded objects can be solved with the electricfield integral equation (EFIE). Compared with other two-region formulations(TRFs), like the PMCHWT, CTF, the proposed approach shows significant benefits:only the surface electric current density instead of both the electric andmagnetic current densities is required to model the complex objects.Furthermore, the single electric current density is only enforced on theoutermost boundary of objects. Therefore, the overall count of unknowns can besignificantly reduced, especially when the number of boundaries betweendifferent homogeneous media is large. At last, several numerical experimentsare performed to validate the accuracy and efficiency of the proposed approach.
