单负介质表面的Goos-Hnchen效应

The Goos-Hnchen Effect on the Surface of Single-Negative Medium

从电磁场基本方程出发推导得到单负介质表面的Goos-Hnchen位移和相移的计算公式,发现:电磁波以任意入射角投射到单负介质表面时只能发生全反射,不存在临界角。对它们进行的数值计算中得出,单负介质表面的Goos-Hnchen位移、相移的符号和大小随入射角大小以及单负介质的介电常数或磁导率的正负的改变而做周期性变化。

The reflection from a half-space filled with an isotropic,homogeneous,weakly dissipative,Single-Negative medium.It is shown here that alinearly polarized beam can experience either a negative or a positive Goos-Hnchen shift.The sign of the shift depends on the incidence angle as well as on the signs of the permittivity or the permeability of the Single-Negative Medium.
