An Optically Transparent Ultrabroadband Microwave Absorber

An Optically Transparent Ultrabroadband Microwave Absorber

An optically transparent ultrabroadband microwave absorber was proposed and experimentally verified, which achieved 23.4-GHz deep absorption bandwidth (absorption >0.8 from 15.6 to 39.0 GHz). What is more, the whole absorber is transparent in the visible light range (transmittance >0.8...
