摘要
基于Dirichlet-to-Neumann(Dt N)映射提出了一种有效的数值方法来计算周期排列的液晶柱的透射/反射光谱。利用各向异性光子晶体单元晶格的Dt N映射,避免了在单元晶格内部进行计算,从而得到一个较小的线性方程组并进行求解。在数值算例中,通过模拟光波在真空中周期排列的液晶柱以及液晶填充的多孔板中的传播状况,验证了液晶填充制造的各向异性光子晶体元件具有可调控性。
An efficient numerical method was proposed for calculating transmission/reflection spectra for the periodic arrays of liquid crystal cylinders by the Diriehlet-to-Neumann（DtN） maps. DtN maps of the unit cell of anisotropie photonie crystals were used to avoid computations in the interiors of the unit cells, and obtained a relative small system of linear equations. In numerical examples, light propagation through the periodic arrays of liquid crystal cylinders in vacuum and the slab filled with liquid crystals was simulated to verify the tunability of anisotropic photonie crystal structures which filled with liquid crystals.
