Structured metal film as a perfect absorber

Adv Mater. 2013 Aug 7;25(29):3994-4000. doi: 10.1002/adma.201300223. Epub 2013 May 10.

Abstract

A new type of absorber, a four-tined fish-spear-like resonator (FFR), constructed by the two-photon polymerization process, is reported. An absorbance of more than 90% is experimentally realized and the resonance occurs in the space between the tines. Since a continuous layer of metallic thin film covers the structure, it is perfectly thermo- and electroconductive, which is the mostly desired feature for many applications.

Keywords: absorbers; electromagnetic wave; magnetic resonance; metamaterials.
