Attend in Zoom

An ultra-wideband terahertz absorber is presented with dielectric hemi-ellipsoid on a monolayer graphene layer. The absorber has achieved an ultra-wideband absorption bandwidth from 2 THz to more than 10 THz with an average absorbance of 95.72%, the relative bandwidth reaches 133%. The excellent absorption properties owing to multiple discrete graphene plasmonic resonances(GPRS) and the continuous multimode Fabry-Perot (FP) resonances, the mechanism for the its ultra-wideband absorption are analyzed in details.
