A broadband and polarization-insensitive perfect absorber based on a van der Waals material in the mid-infrared regime
A broadband and polarization-insensitive optical absorber based on van der Waals (vdW) material h-BN is proposed in the mid-infrared regime. By utilizing the finite-difference time-domain (FDTD) simulation, the broadband absorption spectrum above 95% is achieved from 6490 to 7295 nm. Moreover, the p...
