Optical black hole: Broadband omnidirectional light absorber

We develop an approach to broad-band omnidirectional light absorption, based on light propagation in a metamaterial structure forming an effective "black hole." The proposed system does not rely on magnetic response, is nonresonant, and can be fabricated from existing materials.
