Multichannel unidirectional perfect absorbers on sandwich structures with truncated symmetric photonic crystals
We experimentally studied unidirectional perfect absorbers with asymmetric sandwich structures composed of two thick metallic films with different thicknesses and a truncated symmetric photonic crystal (PC). Single-channel and multichannel near-perfect absorbers were obtained by adjusting period num...
