摘　　要：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.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-Hanchen shift at the inner interface was investigated. The refraction conditions and the sign of the Goos-Hanchen shifts were theoretically analyzed. It is found that the Goos-Hanchen shift of the reflective wave is the same as that of the transmission one, the Goos-Hanchen 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-Hanchen 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 G oos-Hanchen 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.
