Analysis of modes in pairing of single-negative material

摘要: 研究了双层单负材料结构中电磁波的模式,主要分析了不同模式的产生条件,讨论了这些模式与材料参数之间的关系.当材料参数满足平均介电常数和磁导率为零时出现隧穿模式.当满足波导模产生条件时,波导模式的电磁波在材料两边的半无限真空中以消逝波存在,在双层单负材料的界面处也可以出现较强的局域场.

Abstract: The modes in a double-layer of single-negative material have been investigated.The conditions for the existence of different modes have been analyzed.The relations between different modes and material parameters are considered.Tunneling mode appears when the general zero average permittivity and permeability conditions are satisfied.When the wave guide condition is satisfied,electromagnetic wave is evanescent outside the material,and the field is mainly localized at the interface of the two single-negative layers.
