摘　　要：High-temperature stealth is vital for enhancing the concealment,survivability,and longevity of critical assets.However,achieving stealth across multiple infrared bands—particularly in the short-wave infrared(SWIR)band—along with microwave stealth and efficient thermal management at high temperatures,remains a significant challenge.Here,we propose a strategy that integrates an IR-selective emitter(Mo/Si multilayer films)and a microwave metasurface(TiB2–Al2O3–TiB2)to enable multi-infrared band stealth,encompassing mid-wave infrared(MWIR),long-wave infrared(LWIR),and SWIR bands,and microwave(X-band)stealth at 700℃,with simultaneous radiative cooling in non-atmospheric window(5–8μm).At 700℃,the device exhibits low emissivity of 0.38/0.44/0.60 in the MWIR/LWIR/SWIR bands,reflection loss below−3 dB in the X-band(9.6–12 GHz),and high emissivity of 0.82 in 5–8μm range—corresponding to a cooling power of 9.57 kW m^(−2).Moreover,under an input power of 17.3 kW m^(−2)—equivalent to the aerodynamic heating at Mach 2.2—the device demonstrates a temperature reduction of 72.4℃ compared to a conventional low-emissivity molybdenum surface at high temperatures.This work provides comprehensive guidance on high-temperature stealth design,with far-reaching implications for multispectral information processing and thermal management in extreme high-temperature environments.
