Abstract

A glimpse of the efficacy of phase change medium (PCM)-based layered hyperbolic metamaterial (HMM) was emphasized following the analytical investigation of wave propagation through the system. The optical response of HMM was characterized solely by adjusting the materials electrical constants and/or structural parameters, such as the thickness and/or filling fraction. The HMM embedded with graphene and stibnite (Sb2S3) PCM was investigated for angle-invariant, polarization insensitive properties with an in-band rejection over –30 dB, which is tunable in a wavelength span of nearly 50 nm.
