摘要
对二维光子晶体的电磁波理论及周期介质中的 Bloch波解作了详细的推导 ,给出了光子晶体中的禁带存在的理论依据 ,同时以正方晶格的二维光子晶体为例 ,验证了电介质圆柱在空气中的排列存在 E偏振和 H偏振的光子带隙重叠区 ,称为绝对光子带隙 .
This article gives a complete deduction for the electromagnetic wave theory of photonic crystal of two dimensions and Bloch wave solution in stratified periodic dielectric,offers the academic foundation of the existence of stop band by giving an example of two dimensional photonic crystal of square lattice,and demonstrates that dielectric rods in air background can generate a common band gap,which is called absolute photonic band gap,for both orthogonal polarization E and H.
