High-Temperature Stealth Across Multi-Infrared and Microwave Bands with Efficient Radiative Thermal Management.

ABSTRACT: 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 °C, with simultaneous radiative cooling in non-atmospheric window (5-8 μm). At 700 °C, the device exhibits low emissi
