Abstract
The document discloses transferrable hyperbolic metamaterial particles (THMMP) that display broadband, selective, omnidirectional absorption and can be transferred to secondary substrates, allowing enhanced flexibility and selective transmission. A device having metamaterial nanostructures includes a substrate and metamaterial nanostructures engaged to the substrate to form an optical layer to interact with light incident to the optical layer to exhibit optical reflection or absorption or transmission that is substantially uniform over a spectral range of different optical wavelengths associated with materials and structural features of the metamaterial nanostructures, each metamaterial nanostructure including different material layers that are interleaved to form a multi-layer nanostructure.
