Space-to-ground infrared camouflage with radiative heat dissipation

Abstract With the development of space exploration and exploitation, it is imperative to address the potential threats posed to space objects, particularly ground-based infrared observation. However, in the extreme space environment, achieving infrared camouflage across different bands with simultaneous thermal management is challenging and has so far slipped out of concern. Here, we propose the space-to-ground infrared camouflage strategy, compatible with radiative heat dissipation. Camouflage in the H, K, mid-wave-infrared (MWIR), and long-wave-infrared (LWIR) bands is achieved through a multilayer structure, with radiative heat dissipation in the very-long-wave-infrared (VLWIR) band. High absorptivity…
