Hierarchical visible-infrared-microwave scattering surfaces for multispectral camouflage

Abstract Multispectral camouflage, especially for the infrared-microwave range, is an essential technology safety of facilities, vehicles, and humans. So far, it has been realized mainly by high infrared specular reflection microwave absorption. However, external sources can expose target through reflection; also, heat production from absorption increase radiation. This work proposes a multispectral camouflage scheme based on hierarchical visible-infrared-microwave scattering surfaces to address these issues. The proposed device exhibits: (1) low emissivity ( ? 8–14 ?m = 0.17) reflectivity R s 0.13), maintaining radiation capability overcome presence source simultaneously; (2) in with ?10 dB radar cross section reduction bandwidth 8–13 GHz, simultaneously achieving reducing production; (3) tunability color visible camouflage. method control over bands, thereby introducing new design paradigm modern technology.
