Abstract Camouflage is essential in modern security and military operations, playing a critical role in evading detection and enhancing the survivability of equipment. However, most existing camouflage devices operate in a single dimension, rendering them inadequate against emerging multi-dimensional detection techniques, including visible to near-infrared (VIS-NIR) hyperspectral imaging and mid-infrared (MIR) polarization imaging. In this work, we propose a multi-dimensional camouflage strategy that realizes simultaneous VIS-NIR spectrum camouflage, MIR intensity, and polarization camouflage by a hierarchical structure. The multi-dimensional camouflage device exhibits an emissivity of 0.7, a low degree of linear polarization (96.9%) in the VIS-NIR range. Moreover, it deceives hyperspectral classification in vegetative background and blends into its environment under MIR intensity and polarization imaging. This work introduces a novel paradigm for multi-dimensional camouflage techniques and opens up new avenues for electromagnetic waves manipulation.
