A purely plane-wave based fast algorithm is presented for layered media problems. As long as the steepest descent path for the 2-D translator is well defined, the accuracy can be maintained under the MFLMA paradigm, and ultimately achieves the same computational complexity as the mixed form fast inhomogeneous plane-wave algorithm (FIPWA). The advantage is that multipoles are not needed, which makes...
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
A new surface integral equation (SIE) formulation is proposed in this work by tuning the coefficients for the external and internal equations. The present formulation provides satisfactory performance over a significantly larger range of skin depths than existing SIE formulations. It is also confirmed that the mesh density does not necessarily follow the increasing wavenumber for the conductive region...
