Disclosed are methods to produce composite materials, which contain customized mixes of nano- and/or micro-particles with tailored electromagnetic spectral properties. In some defense-related applications, the use of such materials enables an improved spectral match between different structures, such as vehicles or buildings with the surrounding environment at least in the VIS and NIR wavelength range. This can camouflage the structures, and reduce the detectability thereof by ground-, air- or space-based multi-spectral long-range imaging systems, including aircrafts, drones, and satellites, and thus, generally delay, complicate, or eliminate detection or classification of the camouflaged structures.
