Abnormal behaviors of Goos–Hanchen shift in hyperbolic metamaterials made of alu

In this paper, the Goos–Hanchen shift (GHS) at the interface between air and the aluminum zinc oxide (AZO)/ZnO hyperbolic metamaterial (AZO-HMM) is theoretically examined. The results herein show that AZO-HMM can enhance the GHS at the interface to a value at 3 orders of the incident wavelength unde
