A hybrid perfectly matched layer — Spectral element boundary integral method for periodic/non-periodic analyses

A novel perfectly matched layer — spectral element boundary integral (PML-SEBI) method is proposed for integrated analysis of periodic and non-periodic structures in stratified background. The proposed numerical scheme hybridizes the perfectly matched layer and the surface integral equations (SIE's) for lateral and top/bottom boundaries, respectively. This hybrid method avoids the singularity issues in dyadic layered medium Green's function, while maximumly integrating the periodic and non-periodic solvers together.
