High‑Temperature Stealth Across Multi‑Infrared and Microwave Bands with Efficient Radiative Thermal Management (IMAGE)
Caption
- Simultaneous stealth across multiple infrared bands (short-wave infrared (SWIR), mid-wave infrared (MWIR), long-wave infrared (LWIR)) and microwaves at high temperatures (700 °C) is achieved.
- At 700 °C, the device features low emissivity of 0.38/0.44/0.60 in MWIR/LWIR/SWIR bands, reflection loss below − 3 dB in the X-band (9.6–12 GHz), and high emissivity of 0.82 in the 5–8 μm range.
- Under an input power equivalent to Mach 2.2 aerodynamic heating, effective thermal management achieves a 72.4 °C temperature reduction compared to conventional low-emissivity molybdenum.
