Radiation-Absorbing Materials and Surfaces
Researchers at Purdue University have developed a technology that allows dramatic reduction of radiation reflectivity due to the enhanced scattering of light into metamaterials with hyperbolic dispersion. This enhancement is caused by the broadband singularity of the density of states in such hyperbolic metamaterials. This novel technology does not rely on resonance (broadband), is potentially inexpensive to manufacture in any quantities, and does not require magnetic response.
