Paper Abstract

We have numerically presents a perfect graphene metasurface based solar absorber in the frequency range from 100 THz to 1200 THz. The periodically arranged C-shaped in the 3x3 matrix above the graphene monolayer sheet helps to absorb incoming electromagnetic radiation and thus result in increasing absorption. The absorber gives broadband average absorption with 82.7% in infrared (280 THz to 380THz), 86.5% (430 THz to 770 THz) in the visible and 93% in ultraviolet (780 THz to 1000 THz) regions. The band of absorption varies from lower to higher in terahertz range and vice-versa by changing the parameters changes. This tunability makes the proposed based absorber to be used in optical sensors.
