Abstract

In this work, we have theoretically investigated the tunable non-specular effects, specifically Imbert-Fedorov and Goos-Hänchen shifts, on a graphene-based uniaxial hyperbolic crystal geometry. The hyperbolic crystal is made of hexagonal boron nitride and the source of excitation is a circularly polarized light beam. The influence of chemical potential and absolute temperature of the graphene on these effects is examined. Notably, the research reveals that the shifts exhibit complex and significantly varying behavior within and outside the infrared reststrahlen frequency-bands of hyperbolic crystal.
