| 摘 要： | 基于对光子晶体禁带影响因素的研究，设计了圆弓形和非对称圆弓形两种新型散射元。并利用平面波展开法，根据六边形排列结构，对两种新型散射元禁带宽度进行模拟计算，比较了TE模式和TM模式禁带关系和相对禁带宽度。结果表明，两种新型散射元不但可以获得更大的光子晶体禁带宽度，而且可以方便地调整禁带的位置。

| Abstract: | Two kinds of new scatterers,symmetric cylindrical-segment scatterers and asymmetric cylindrical-segment scatterers,were designed through analyzing of the effect factors for photonic crystal bandgaps.Based on the ordered hexagonal structure,the bandgaps were calculated by plane wave expanding method.Results show that two kinds of new scatters not only can make larger bandgaps of photonic crystal,but can change easily the location of the bandgaps. |

| Keywords: | photonic crystal cylindrical-segment scatterer asymmetric cylindrical-segment scatterer bandgap |
