Abstract: 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.

Broadband polarization-independent resonant light absorption using ultrathin plasmonic super absorbers
TL;DR: An ultrathin (260 nm) plasmonic super absorber consisting of a metal-insulator-metal stack with a nanostructured top silver film composed of crossed trapezoidal arrays yields broadband and polarization-independent resonant light absorption over the entire visible spectrum.
Transformation optics and metamaterials
TL;DR: The potential of transformation optics to create functionalities in which the optical properties can be designed almost at will is reviewed, which can be used to engineer various optical illusion effects, such as the invisibility cloak.

Dark acoustic metamaterials as super absorbers for low-frequency sound
TL;DR: A thin-film acoustic metamaterial, comprising an elastic membrane decorated with asymmetric rigid platelets that aims to totally absorb low-frequency airborne sound at selective resonance frequencies ranging from 100-1,000 Hz, can reach almost unity absorption at frequencies where the relevant sound wavelength in air is three orders of magnitude larger than the membrane thickness.

TL;DR: In this article, it is shown that metallic gratings can exhibit anomalies which consists of total absorption of a plane wave. But this is not the case for all grating anomalies.
