摘要：

A novel implementation of periodic boundary conditions incorporated into the finite-difference time-domain (FDTD) technique in both orthogonal and nonorthogonal grids is presented in this paper, The method applied is a field-splitting approach to the discretization of the Floquet-transformed Maxwell equations, As a result, computational burden is reduced and the stability criterion is relaxed, The results of the two methods are compared to experimental data.
