二维正方复式晶格的完全光子带隙

Absolute photonic band gaps of 2-D cubic compound lattice

为产生光子晶体完全光子带隙 ,在二维正方晶格的介质柱中心构造一个空气柱孔缺陷 ,应用平面波展开的方法研究了光波在其中的传播规律 ,发现在特定的结构参数条件下 ,该结构产生了完全光子带隙 。

In order to obtain the absolute photonic band gaps,we design a two-dimension cubic compound lattices made of dielectric cylinders with an air hole in their centers and study its photonic band structures with the plane-wave method. An absolute photonic band gaps common to E and H polarized waves are created when given proper structure parameters,which tells us that absolute photonic band gaps can be created from a simple lattice.
