Hierarchical visible-infrared-microwave scattering surfaces for multispectral camouflage.

ABSTRACT: Multispectral camouflage, especially for the infrared-microwave range, is an essential technology for the safety of facilities, vehicles, and humans. So far, it has been realized mainly by high infrared specular reflection and high microwave absorption. However, external infrared sources can expose the target through specular reflection; also, the heat production from microwave absorption can increase the infrared 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 infrared emissivity (ε _8-14 μm = 0.17) and low infrared specular reflectivity (R _{s 8-14 μm} = 0.13), maintaining low infrared radiati
