Metasurface Camouflage Skin for Simultaneously Deceiving Multispectral Imaging and Radar Detection

ABSTRACT The proliferation of advanced photoelectric detectors and multi‐spectral reconnaissance platforms has invalidated single‐mode camouflage, necessitating synchronous deception across visible, infrared and radar bands. Here, we introduce resonant regulation paradigm into the multi‐dimensional camouflage metasurfaces with single‐functional‐layer (analogous to biological skin), enabling them to achieve integration and synchronization across multiple spectra. Leveraging this strategy, two types of simple but effective single‐structural cascaded metasurfaces are designed to achieve collaborative illusion deception disguise and low detectable camouflage. As a proof‐of‐concept, two types of metasurfaces capable of generating the illusion of an “airplane” are designed and fabricated. In microwave band (8–12 GHz), the metasurfaces can achieve imaging camouflage in near field and scattering reduction in far field. In infrared band (8–14 µm), the infrared thermal illusion patterns are customized by arranging the meta‐atoms with low and high emissivity. In visible light band (400–800 nm), the “airplane” patterns can be observed clearly due to the different surface patterns of meta‐atoms. By synergizing resonant coupling and decoupling with their matching holographic imaging engines, these metasurfaces in this work concurrently condense structural simplicity and multidimensional camouflage functionality into a single layer, which may trigger further innovation in the design and application of compact multispectral camouflage devices.
