Polarization-Independent Tunable Ultra-Wideband Meta-Absorber in Terahertz Regime
In this paper, we demonstrate an ultra-broadband terahertz bilayer graphene-based absorption structure. It has two stacking graphene layers sandwiched by an Au cylinders array, backed by a metallic ground plane. Au cylinders are used to adjust the input impedance to be closely matched to the free sp...
