Abstract

An efficient wideband finite-difference time-domain (FDTD) method is proposed to analyze arbitrarily skewed periodic structures at oblique incidence. The method is free of complex step-by-step phase processing caused by the oblique incident plane wave and the stagger unit cells, and the provided periodic boundary condition (PBC) is as simple to implement as in the normal incidence case. A numerical example is simulated respectively by our method in one-time calculation over a wideband and the previous dual plane wave method requiring multiple repeated runs, which verifies the validity and efficiency of the proposed method.
