构造了(AB)N(BA)N对称型两种单负材料交替一维光子晶体,利用传输矩阵法进行数值模拟.结果表明:这种单负交替对称型一维光子晶体具有一种特殊带隙结构,该带隙不敏感于入射角和晶格的无序性.在该带隙内出现了两个隧穿模,该隧穿模不敏感于入射角的改变和晶格的无序性,但能带及带隙内的隧穿模却敏感于晶格标度和周期数的变化;随着入射角的改变,带隙两侧的隧穿模趋于简并.这些特性对在利用此结构光子晶体设计双重超窄带滤波器时,具有一定的参考价值. The one-dimensional (2D) N (BA) N symmetric one-dimensional photonic crystals with one negative material were constructed by the transfer matrix method. The results show that the one- Gap structure that is not sensitive to the angle of incidence and the disorder of the lattice In the band gap there are two tunneling modes that are insensitive to the change of the incident angle and the disorder of the lattice , But the tunneling modes in the bandgap and bandgap are sensitive to the lattice scaling and the number of cycles. The tunneling modes on both sides of the bandgap tend to degenerate with the change of the incident angle, This structure photonic crystal design double super narrow band filter, has a certain reference value.
