Angular Goos-Hänchen shift due to an epsilon-near-zero slab
We examine the angular Goos-Hänchen shift on an epsilon-near-zero (ENZ) metamaterial as the angle of incidence and the thickness of the slab is changed. In our calculations, s- and p-polarized light source propagating in vacuum is incident on a lossless and lossy ENZ slabs. Our results show very large magnitude of ΘGH on specific angle of incidence and slab thickness. Increasing the loss in the material also increases the magnitude of the shift. The large ΘGH shifts could be used to explore the development of a high sensitivity ENZ-based sensor.
