Abstract

The application discloses a multifunctional terahertz chiral super surface based on vanadium dioxide and graphene, which is arranged by a periodic array of M*N super surface units with a multilayer structure, and the super surface units are distributed in two dimensions of M*N, wherein M and N are positive integers; the super surface unit comprises, from bottom to top, a metal substrate, a first dielectric layer, a graphene layer, a second dielectric layer and a resonance layer unit. The super surface realizes efficient multifunctional response by reasonably utilizing the phase transition characteristics of VO2 and the tunability of graphene, and solves the problems of few functions, single regulation mode and low efficiency of traditional super surfaces. The application further provides a preparation method of the multifunctional terahertz chiral super surface based on vanadium dioxide and graphene.
