A tunable flat terahertz lens using Dirac semimetals: a simulation study
Abstract We propose and design a flat and tunable terahertz lens achieved through a two-dimensional photonic crystal composed of an array of rods made of a Dirac semimetal placed in air as the background medium. The structure of interest is a graded index photonic crystal, made possible by the sligh...
