Various FDTD approaches has been applied in the analysis of periodic structures, among which Spectral FDTD is a straight-forward and robust one. This essay proposed an improved Spectral FDTD algorithm that improves the simulation speed of off-normal incident case without jeopardizing accuracy. Together with GPU accelerating, as is proven by the example, the proposed acceleration scheme offers a speedup of 22 at minimum.
