利用传输矩阵法分析一维光子晶体中亚波长缺陷膜对缺陷模频率处Goos-Hnchen位移的调制特性,讨论了亚波长缺陷膜的厚度、磁导率及介电常量对一维光子晶体缺陷模频率处的Goos-Hnchen位移的影响.研究发现:一层几何厚度极小的亚波长薄膜即可非常灵敏地调制一维光子晶体缺陷模频率处Goos-Hnchen位移的位置及其大小;并且当亚波长缺陷膜为左手材料时,Goos-Hnchen位移随亚波长缺陷膜物理参量的变化趋势与普通右手材料时的情形完全相反. The modulation characteristics of the Goos-Hönchen displacement at a defect mode frequency of a sub-wavelength photonic crystal in a one-dimensional photonic crystal are analyzed by using a transfer matrix method. The effects of the subwavelength defect film thickness, permeability and dielectric constant on the one-dimensional photonic crystal The effect of the Goos-Hönchen displacement at the defect mode frequency is studied. The results show that the sub-wavelength thin film with very small geometrical thickness can very sensitively modulate the position of the Goos-Hönchen displacement at the mode frequency of the one-dimensional photonic crystal defect Its size, and when the subwavelength defect film is a left-handed material, the trend of the Goos-Hönchen shift with the sub-wavelength defect film physical parameter is completely opposite to that of the normal right-handed material.
