Abstract

In this paper, we propose an ultra-thin metasurface to achieve simultaneous thermal infrared camouflage and 1.06 μm laser scattering with thermal management. First, the metasurface has an average absorptivity/emissivity of 0.04 in the band of 8~14 μm and a emission peak at 5.62 μm with nearly 100% emissivity. Therefore, camouflage against thermal infrared detectors and effective thermal management can be achieved. Second, the chessboard-like square patches on the top of the meatsurface make it possible to reduce the specular reflection at the laser wavelength of 1.06 μm to less than 2% by redirecting the reflected light to non-normal angles. These excellent simulated results indicate that our proposed metasurface has promising applications in the fields of multi-band infrared camouflage.
