作为一种特殊的光学现象,对一定的光学结构，Goos-Hänchen(GH)位移与构造材料密切相关.对电介质/超导/电介质这一结构，本文给出了GH 位移在超导材料为近零折射率材料时随入射角、光波长和超导层厚度等参数的变化曲线.结果表明，GH 位移随上述参数的变化规律，与超导材料折射率为零时的波长( 阈值波长) 相关联，波长大于和小于阈值波长时的变化规律存在一定的差异.近零折射率材料在光子学领域具有广泛的应用.计算结果为新型光子学器件研究开发提供了参考.论文对大学生理解近零折射率概念，以及近零折射率区超导材料的Goos-Hänchen位移也有所帮助.

As a special optical phenomenon，the Goos-Hänchen (GH) shift is closely related to the construction material for a certain optical structure. For the dielectric /superconductor /dielectric structure，the variation curves of the GH shift with the incident angle，the wavelength of light and the thickness of the superconducting material layer are given when the superconducting material is the near-zero refractive index material. The results show that the variation of GH shift with the above-mentioned parameters is related to the threshold wavelength which is defined as the wavelength at which the refractive index of the superconducting material is zero. It is found that there is a certain difference for the GH shift when the wavelength is greater than or less than the threshold wavelength. Near-zero refractive index materials have a wide application in the field of photonics. The calculation results provide a useful reference for the research and development of new photonic devices. The paper also helps undergraduates to understand the concept of near-zero refractive index and the GH shift of superconducting materials in the near-zero refractive index region.
