| 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. |

| Keywords: | finite difference time domain method excitation source two-dimensional photonic crystal transmissioncoefficient |
