电磁波在双轴左手介质中的异常反射和折射

Anomalous Reflection and Refraction of Electromagnetic Wave in Biaxial Left-handed Materials

讨论了电磁波在双轴左手介质中的传播和电磁波在普通介质与双轴左手介质界面上的反射和折射.当ε22<0,μ11>0,μ33>0(μ22<0,ε11>0,ε33>0)时,电极化波(磁极化波)在双轴左手介质中不能传播,而在其它情况,电磁波的入射角只有在满足一定条件时才能传播.当电磁波从普通介质入射到双轴左手介质的分界面上时,满足ω2ε22μ33>k2sin2θ(ω2ε33μ22>k2sin2θ)时,电极化波(磁极化波)将发生折射,论文还讨论了在两界面上电磁波发生全反射的条件,这些结果与普通介质与各向同性左手介质界面上的反射不同.

The investigations are presented on the propagation characteristics of the electromagnetic wave in biaxial lefthanded materials（LHM）. This paper discusses the reflection and refraction of the electromagnetic wave surface on a boundary surface between one isotropic regular material and another biaxial LHM. The authors find that electric polarization wave （magnetic polarization wave） can not propagate when ε22〈0,μ11〉0,μ33〉0（μ22〈0,ε11〉0,ε33〉0）. Under the other conditions, only when the incident angle of the incident electromagnetic wave fits certain conditions it can propagate.
