Multi-scale regulation of structure and material for visible-infrared-LiDAR multispectral camouflage

Abstract: The development of detection technologies has driven an urgent need for multispectral camouflage capabilities. However, the requirement for multispectral camouflage, including colored visible (VIS) camouflage, adaptive infrared (IR) camouflage, and multi-band laser camouflage, challenges conventional single-design approaches from design to fabrication. Here, we propose a simplified design strategy that enables decoupling between material and structural regulation, thereby enhancing multiband modulation performance. From visible to near-infrared (NIR) bands, thin-film Fabry–Pérot cavities facilitate simultaneous visible structural color and NIR laser band absorption. The calculated VIS results are in excellent concordance with experimental ones (ΔĒ < 6). Experimental measurements further demonstrate broadband (900 nm-1550 nm) ultra-high absorption in the NIR band. The orders-of-magnitude difference in wavelengths enables structural dimensions decoupling, effectively separating the influence of the architecture on visible and mid-infrared (MIR) performance. In the MIR region, the metadevice realizes adaptive infrared thermal camouflage with laser camouflage based on phase-change material.
