In this article, we have theoretically investigated the performance of graphene-hexagonal Boron Nitride (hBN) multilayer structure (hyper crystal) to demonstrate all angle negative refraction along with superior transmission. hBN, one of the latest natural hyperbolic materials, can be a very strong contender to form a hyper crystal with graphene due to its(More)
In this article, we have theoretically proposed and numerically analysed a resonant wavelength tunable Fabry Perot (FP) filter without changing the physical length of the cavity in the mid-infrared range. The proposed FP filter consists of a multilayer cavity, which is constructed by alternately repeating two different sub-wavelength dielectric or(More)
