对正负折射率材料构成的一维光子晶体，在横向圆形受限的条件下，推出了光波在其中传播时模式所满足的条件，并利用特征矩阵法研究了正负折射率绝对值相同时，光波在不同模式和不同介质厚度可见光能实现透射波和零反射。正负折射率绝对值不等时，得出介质厚度为半波长时透射波出现在中心波长处；随着模式数即入射角增大，透射波曲线向短波方向移动；介质折射率差的绝对值越大、周期数增加都使透射波谱宽度变窄。

The conditions to different patterns were obtained for light wave propagating in onedimensional lateral circular restricted photonic crystal with negative index. Transmission wave was studied by characteristic matrix for different patterns and different media thicknesses when the refractive index absolute value is equal. For unequal refractive index absolute value, the peaks of transmission wave appear at the center wavelength when the medium thickness is the half wavelength. With the increase of the periods and the absolute value of refractive index difference, the full width at half maximum of spectrum decreases.
