左手材料复合双棱镜内部界面的古斯-汉森位移

设计了一种左手材料复合双棱镜,由两块各向同性左手材料棱镜与夹在其间的、其界面与光轴成一定的角度的单轴各向异性左手材料平板构成.研究了发生在其内部界面上的古斯-汉森位移.分析了发生折射的条件和古斯-汉森位移的符号.研究发现,反射波与透射波有相同的古斯-汉森位移,透射波的古斯-汉森位移随着薄层厚度的增加而振荡,整体上呈增加趋势；在透射共振点,透射波的古斯-汉森位移达到极大值,且极大值可达入射波波长的数十倍；发现入射角和光轴与界面的角度对透射波的古斯-汉森位移有很大影响.最后简单地探讨了这种双棱镜的潜在应用.

Goos-Hanchen Shift at the Inner Interface of a Composed Rhomboid Prism Made of Left-handed Materials

A composed rhomboid prism composed of two isotropic left-handed material (LHM) prisms with an uniaxially anisotropic LHM plate,there is an angle between the interface of which and the optical axis,was designed.The Goos-Hnchen shift at the inner interface was investigated.The refraction conditions and the sign of the Goos-Hnchen shifts were theoretically analyzed.It is found that the Goos-Hnchen shift of the reflective wave is the same as that of the transmission one,the Goos-Hnchen shift of transmission wave oscillates with the thickness of the film increasing,and its overall tendency increases,At the resonance point of the transmission wave ,the Goos-Hnchen shift of transmission wave reaches its maximum which is almost several tens of the wavelength of the incident wave.It is also found that the Goos-Hnchen shift of transmission wave is significantly affected by the incidence angle and the angle between the optical axis and the interface.Finally,the potential applications of this prism is briefly discussed.
