In this paper, we use the rotating elliptical Gaussian beams (REGBs) to impinge the surfaces coated with cross-anisotropic metasurfaces (CMs) to investigate the Goos–Hänchen (GH) and Imbert–Fedorov (IF) shifts. The effect of the CM coating on the reflection coefficient in this system is considered. In particular, we will show that the angle of incidence and the relative permittivity of the weakly absorbing medium have an influence on the GH and the IF shifts. A comparison with the case of surfaces without the CM is also discussed.

Goos-Hänchen 和 Imbert-Fedorov 从涂有交叉各向异性超表面的表面反射的旋转椭圆高斯光束的位移

在本文中，我们使用旋转椭圆高斯光束 (REGB) 撞击涂有交叉各向异性超表面 (CM) 的表面，以研究 Goos-Hänchen (GH) 和 Imbert-Fedorov (IF) 位移。考虑了共模涂层对本系统反射系数的影响。特别是，我们将证明弱吸收介质的入射角和相对介电常数对 GH 和 IF 偏移有影响。还讨论了与没有 CM 的表面情况的比较。
