摘要
将时域有限差分方法用于光子晶体传输特性理论研究 ,分别计算了二维方型光子晶体TM模和TE模的透射率频率分布 ;根据光子晶体的标度不变性特征 ,在微波频段制作了光子晶体 ,并设计了实验装置 ;实验结果与计算结果一致表明 :对于一定的入射方向 ,某些频率的光不能在光子晶体中传播。
The finite-difference time-domain (FDTD) method is developed for the study of transmission characteristics of 2-D photonic crystals. Transmitted power of TM mode and TE mode of 2-D square lattice photonic crystals are given. Based on scaling properties of photonic crystals, the photonic crystal behaving in the electromagnetic zones is fabricated and experimentation is designed. The theoretical results confirmed the experimental results. It is shown that the light with a certain frequency and incident direction can not propagate in the photonic crystal.
