Tunable quad-band absorber based on graphene metamaterials

In person: 11 October 2021 • 13:00 - 14:30 China Standard Time

Abstract

High performance absorber is desirable for solar energy, photo detection and optical interconnects. Here an active tunable graphene metamaterials quad-band absorber is theoretically demonstrated. The designed absorber has four higher than 97% absorption peaks in terahertz and infrared range. This absorber consists of a graphene layer, a silica substrate and a metal reflective surface. Simulation demonstrates that absorbance peak can be adjusted by changing geometric parameters of the periodic array structure or the Fermi level of the graphene. Such devices may have potential application in active plasmonic sensor, Light detection, photo thermal conversion and optoelectronic devices.
