    Abstract

    Based on the transparent conductive material Indium Tin Oxide (ITO) and highly transparent Polyethylene Terephthalate (PET), optically transparent ultra-wideband radar and infrared compatible stealth hybrid metasurfaces were achieved. Two specically designed optically transparent metasurfaces were combined to realize radar and IR bi-stealth. One was designed to control the microwave absorption though properly modifying the impedance and resonance peaks of the meta-atom. The other was empolyed to control the IR radiation.The absorptivity in the microwave band 8.0~32.0 GHz band is greater than 90%, and its infrared stealth performance and heat radiation characteristics are further studied.
