为了研究消逝波在常规介质构成的无缺陷的1维光子晶体中的传输特性，采用特征矩阵法进行数值计算。得到在入射角大于全反射临界角时，在很宽的禁带背景中, 透射谱存在一系列通带的结果。 每个通带由分离的透射峰组成；电磁波是以微腔共振模通过消逝波耦合的方式传播。结果表明，利用消逝波的这种传输特性，可以设计高Q值多通道滤波器。

The transmission properties of evanescent wave in ordinary 1-D photonic crystal were simulated by means of the eigen matrix method. In wide gap, there are a series of transmission bands composed of some discrete peaks. The transmission mode comes from localized resonant modes through evanescent wave coupling. The results indicate that these discrete transmission peaks can be used as multi-channel filter with high Q value.
