We present a tunable spin Hall effect of light (SHEL) by introducing a monolayer of graphene on the hexagonal boron nitride (hBN). The interaction between the phonon polaritons in hBN and the plasmon polaritons in graphene can significantly enhance the SHEL around epsilon-near-zero (ENZ) near reststrahlen band-I (RB-I) in a very wide range of incident angles and compress it obviously ... https://www.southsideprintingservice.com/product-category/filter-plugs/
