正、负古斯-汉臣位移和负相--速度介质(又称左手材料)

Positive and Negative Goos-Hanchen Shifts and Negative Phase--Velocity Mediums (alias Left-Handed Materials)

A. Lakhtakia

摘要:

本文研究了线偏振光束在充满各向同性、均匀、弱耗散、具有负相速度特性的介质-磁介质的半空间中的全反射,得到了线偏振光束的古斯-汉欣位移既可以是负的,也可以是正的。偏移的符号取决于光束的偏振状态以及NPV介质的介电常数和磁导率的实部的符号。

英文摘要:

On total reflection from a half-space filled with an isotropic, homogeneous, weakly dissipative, dielectric-magnetic medium with negative phase-velocity (NPV) characteristics, it is shown here that a linearly polarized beam can experience either a negative or a positive Goos-Hanchen shift. The sign of the shift depends on the polarization state of the beam as well as on the signs of the real parts of the permittivity and the permeability of the NPV medium.
