Fig. 1: Atmosphere transmittance and scheme for multispectral camouflage.
From: Multispectral camouflage for infrared, visible, lasers and microwave with radiative cooling
a Atmosphere transmittance spectrum for the electromagnetic wave (from visible to microwave) with detectable ranges indicated by dashed boxes and arrows. The IR part (1–14 μm) is magnified and shown with the ideal absorbance/emittance spectrum. b Requirements of multispectral camouflage for each respective range, and the designed structure with ZnS/Ge multilayer selective emitter for visible, IR, and laser camouflage and Cu-ITO-Cu absorptive metasurface for microwave camouflage.
