摘要

Nowadays,multi-functional materials are desperately required for adapting the complex environment,which urges us to take more factors into consideration.Here,we proposed a broadband microwave absorber with multi-functionality such as optically transparent,thermal insulating and soundproof properties.Using indium tin oxide(ITO)based met-amaterial,the device can achieve above 90％microwave absorption from 5.6 GHz to 23 GHz(cover X and Ku band).Moreover,with designed vacuum structure inside,the device is thermal insulating and soundproof.These mul-ti-functional advantages give the absorber more flexibility in electromagnetic shielding and stealth application,which can be potentially applied in windows related industry.
