The paper mainly researches the relationship between photonic band gap and scattering characters of single period.

The methods of bandwidth increasment and the problems of one-dimensional photonic crystal omnidirectionsl reflector are discussed.

讨论了增加禁带宽度的方法及一 维 光子晶体全角度反射镜中存在的问题.

Energy band structures of different magnetic dielectric photonic crystals ( CD ) are calculated by finite-difference time-domain ( FDTD ) method.

利用时域有限差分(FDTD ) 法,计算了磁介质材料光子晶体 ( PC ) 的能带结构.结果表明,磁性散射也能形成光子禁带.

And the gap of the triangular lattice is wider than that of the square array.

同时三角形排列下禁带宽度大于正方形排列.

We study several typical kinds of two-dimensional PCs by using our method.

采用该方法,本文讨论了几类典型的二 维 光子晶体的禁带特性.
