Phys.org  February 7, 2024 Achieving effective camouflage and thermal management across the entire infrared spectrum, especially the short-wave infrared (SWIR) band, remains challenging. Researchers in China proposed a multilayer wavelength-selective emitter that achieves effective camouflage across the entire infrared spectrum, including the near-infrared (NIR), SWIR, mid-wave infrared (MWIR), and long-wave infrared (LWIR) bands, as well as the visible (VIS) band. The emitter would enable radiative heat dissipation in two non-atmospheric windows. The emitter’s properties were characterized by low emittance in the SWIR/MWIR/LWIR bands, and low reflectance in the VIS/NIR bands. The high emittance in the two non-atmospheric windows would ensure […]
