色散负折射特异介质的1维光子晶体缺陷态
Defect states in one-dimensional photonic crystal with dispersive negative refractive index metamaterial
摘要
Abstract
The dispersive negative index metamaterial possesses a negative refractive index in the microwave region(1 to 10 GHz), whose effective permittivity and permeability determine different refractive indexes in different frequency regions. The dispersive negative index metamaterial is introduced into one-dimensional photonic crystal to form two structures: positive index media photonic crystal with negative index metamaterial defect, and positive and negative index media photonic crystal with positive index medium defect. By numerical simulation, transmission spectra are shown for the two structures under homogeneous plane electromagnetic wave (TE wave) normal incidence and oblique incidence, in which single- and dual-defect modes appear in different forbidden bands when both effective permittivity and permeability are negative. These defect modes can be used to realize single- and dual-channel filtering, respectively.关键词
