Angular Goos-Hänchen shift due to an epsilon-near-zero slab

Abstract

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 Θ_GH  on specific angle of incidence and slab thickness. Increasing the loss in the material also increases the magnitude of the shift. The large Θ_GH shifts could be used to explore the development of a high sensitivity ENZ-based sensor.
