Multispectral metal-based electro-optical metadevices with infrared reversible tunability and microwave scattering reduction.

ABSTRACT: The demand for advanced camouflage technology is increasing in modern military warfare. Multispectral compatibility and adaptive capabilities are increasingly desired features in camouflage materials. However, due to the strong wavelength dependence and limited tunability of electromagnetic wave responses, achieving simultaneous multispectral compatibility and adaptive capability in a single structure or device remains a challenge. By integrating coding metamaterials with infrared (IR) electrochromic devices, we demonstrate a highly integrated multispectral metal-based electro-optical metadevice. The fabricated metadevices enable the reversible tunability of IR emissivity (0.58 at 3-5 µm, 0.50 at 7.5-13 µm) and wideband microwave scattering reduction (>10 dB at 10-20 GHz). The excellent in
