Analysis of 2-D Dielectric Photonic Crystals Using the Method of Lines

运用直线法对二维介质型光子晶体的能带结构进行分析,给出直线法中关于二维介质型光子晶体的本征方程的建立过程.同时,对不同参数的光子晶体进行计算,计算结果通过时域有限差分算法(FDTD)及已发表的数据得到了验证,并考虑不同结构的光子晶体的TE波与TM波的带隙形成情况,可为二维介质型光子晶体的设计提供参考.

The bandgap structure of 2-D dielectric photonic crystals is analyzed using the method of lines （MoL）. The eigenvalue equation for 2-D dielectric photonic crystals is derivated. The photonic crystals with different parameters are computed and the results are validated by FDTD and published results. The TE and TM band gaps are considered, which gives a reference to the design of dielectric photonic crystals.
