| 摘 要： | 为了研究柱体截面对二维光子晶体传输特性的影响，应用转移矩阵方法数值计算不同截面形状柱体组成二维光子晶体的透射谱。数值结果表明在一定的入射方向。某些频率的光不能在光子晶体中传播即出现所谓的禁带．禁带的宽度、频率范围、频率中心与光予晶体柱体的截面形状有关。在相同截面时可通过角度调节实现对禁带的微调。

| Abstract: | In order to study the effect of different section on transmission properties of two-dimensional photonic crystals,Transfer Matrix method is used to calculate transmission spectra of two-dimensional photonic crystal composed of different section pole.The calculated results obviously show the existence of band gap,the band gap width,frequency range and center of band gap are related to the shape of pole's section.Litter adjustment of band gap can through angle adjusted at same section. |
