TLDR
This Letter demonstrates, for the first time, selective thermal emitters based on metamaterial perfect absorbers and finds that emissivity and absorptivity agree very well as predicted by Kirchhoff's law of thermal radiation.Abstract:
In this Letter we demonstrate, for the first time, selective thermal emitters based on metamaterial perfect absorbers. We experimentally realize a narrow band midinfrared (MIR) thermal emitter. Multiple metamaterial sublattices further permit construction of a dual-band MIR emitter. By performing both emissivity and absorptivity measurements, we find that emissivity and absorptivity agree very well as predicted by Kirchhoff's law of thermal radiation. Our results directly demonstrate the great flexibility of metamaterials for tailoring blackbody emission.read more

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.

Flexible thin-film black gold membranes with ultrabroadband plasmonic nanofocusing for efficient solar vapour generation
TL;DR: Large area, flexible thin-film black gold membranes are demonstrated, which have multiscale structures of varying metallic nanoscale gaps (0–200 nm) as well as microscale funnel structures that allow heat localization within the few micrometre-thick layer and continuous water provision through micropores.

Ultra-broadband Light Absorption by a Sawtooth Anisotropic Metamaterial Slab
TL;DR: In this paper, an ultra broadband thin-film infrared absorber made of saw-toothed anisotropic metamaterial is presented, where light of shorter wavelengths are harvested at upper parts of the sawteeth of smaller widths, while light of longer wavelengths are trapped at lower parts of larger tooth widths.
