Four peak and high angle tilted insensitive surface plasmon resonance graphene absorber based on circular etching square window

Abstract This article introduces a new type of graphene-based perfect absorber that features tunability across four wave peaks and high sensitivity, consisting of Ag–SiO 2 –graphene. By controlling the Fermi level and relaxation time of graphene, the tunability of the absorber is achieved, and by ch... View More
