【Abstract】 All sort of excitation source numerical simulation of two-dimensional photonic crystal by Finite-Defferce-Time-Domain(FDTD) are analyzed The Influence of pure plane wave source and Gaussian beam source in numerical simulation of two-dimensional photonic crystal is studied.The calculated results show that the transmission coefficient of two-dimensional photonic crystal is not only related to type of wave source but also related to incident angle.更多还原
