色散光子晶体GHz波段的传输特性

将两单负材料耦合后,再与一双负材料交替生成光子晶体。然后利用传输矩阵法对该光子晶体的能带和缺陷模进行了研究。结果表明:这种结构的光子晶体具有一种新型的光子带隙,不随晶格常数的缩放而移动;当引入普通电介质缺陷层时,缺陷模对入射角的改变不敏感,但缺陷模个数随着缺陷层厚度的增加而增多。

Transmission Characteristic of GHz Wave Band in Dispersive Photonic Crystal

By using transfer matrix, the band structures and defect mode of photonic crystals consisting of coupling single-negative materials and double-negative materials were studied. It was shown that this structure can possess a new type of photonic gap, which is invariant with scaling length. When a normal dielectric defect layer was inset, the defect mode is insensitive to the angle of incidence. However, the number of the defect modes increase with the increase of width of defect layer.
