In this paper, the tunable Goos–Hanchen (GH) effect on a graphene-based hyperbolic metamaterial slab has been investigated using the transfer matrix and finite element methods. It was shown that the excitation of the surface polaritons in the THz frequency region results in enhanced GH shift at the interface of the slab which can be controlled and tuned by changing the orientation of the optical axis of the slab, the chemical potential of graphene monolayers and the thickness of the air gap layer. These may have interesting applications in the optical devices.

基于石墨烯的双曲超材料板的 Goos-Hänchen 效应

在本文中，使用传递矩阵和有限元方法研究了基于石墨烯的双曲超材料板的可调 Goos-Hanchen (GH) 效应。结果表明，在太赫兹频率范围内激发表面极化子会导致平板界面处的 GH 位移增强，这可以通过改变平板光轴的方向、石墨烯单层的化学势来控制和调整和气隙层的厚度。这些可能在光学器件中具有有趣的应用。
