为了更全面地认识和了解金属Ag的各种物理性质,对金属Ag的磁光性质进行了研究.利用光隧穿机制分析了由全介质光子晶体.厚金属Ag膜一全介质光子晶体组成的三明治结构的透射和磁光法拉第旋转效应.研究结果表明,由于电磁场局域在光子晶体和厚金属Ag膜的界面上,导致厚金属Ag膜透射和磁光法拉第旋转效应的同时增强.
In order to more comprehensively know and understand the physical properties of the metal Ag, its magneto-optical characteristics are investigated. By using light tunneling mechanism, we study the transmission and magneto-optical Faraday rotation effect of a thick metal Ag sandwiched between two dielectric photonic crystals. The results show that the transmission and magneto-optical Faraday rotation effect of a thick metal Ag can be enhanced, owing to the localized electromagnetic field at the interface between the metal Ag and photonic crystal.
