Dual-controlled tunable terahertz coherent perfect absorption using Dirac semimetal and vanadium dioxide
We proposed and investigated a dual-controlled broadband tunable terahertz metamaterial coherent perfect absorber based on Dirac semimetals and vanadium dioxide (VO2). In such an absorber, the absorptivity at 2.75 THz can be varied between 0.13% and 99.4% by adjusting the phase difference between th...
