Abstract
With the rapid development of detection technology and artificial intelligence, the widespread use of multispectral detectors has increased challenges to stealth capabilities. In this paper, an optically transparent ITO/dielectric/ITO sandwich structure with high microwave absorption and a spatially tunable infrared radiation is designed. The absorption in the 8.1-9.8 GHz band more than 90% in the microwave band is realized. By changing the ITO ratio on the surface of the absorbing layer, a customizable infrared emissivity can be realized. The tunable IR emissivity ranges from 0.2 to 0.7 with good thermal insulation. The structure has good wideband radar absorption, spatially adjustable infrared emissivity and optical transparency characteristics, and has broad application prospects in the field of multispectrum stealth.
