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

Abstract The continuous advancement of electronic devices, driven by trends toward miniaturization, reduced weight, higher integration, and multifunctionality, imposes stringent requirements on the performance electromagnetic wave (EMW) absorbing materials. Traditional EMW absorbers, such as metals, face significant drawbacks, including high density rigidity, which limit their broader application in absorption. To overcome these issues, cellulose is employed matrix, incorporating nickel ferrite (NiFe 2 O 4 ) nanocrystals carbon nanotubes (CNTs) functional fillers. ferrite/CNT/cellulose aerogels (NCCAs) are fabricated through ionic crosslinking room‐temperature drying techniques. results show that porous structure NCCA enhances multiple scattering energy dissipation pathways for EMWs, while CNTs provide excellent electrical dissipation. content NiFe strongly influences aerogel's saturation magnetization parameters NCCAs, primarily owing to superior dielectric magnetic loss properties. Notably, when 4% mass, achieves lowest reflection −66.53 dB at 16.11 GHz, lower than most reported ferrite‐based absorbers. This work provides valuable insights guidance design novel aerogel‐based absorbers with lightweight properties, strong absorption intensities, broad frequency bands.
