中文说明：研究FDTD模拟一维光子晶体中的光波传输，并利用此方法计算了电磁波在一维光子晶体中的电场和磁场的空间分布以及一维光子晶体的透射谱。
English Description：
FDTD is used to simulate the transmission of light wave in one-dimensional photonic crystal. The spatial distribution of electromagnetic wave in one-dimensional photonic crystal and the transmission spectrum of one-dimensional photonic crystal are calculated by using this method.
