Devices consuming the energy of electromagnetic radiation, such as absorbers and sensors, play an essential role in the using and controlling of light. Researchers have now demonstrated the first realization of absorbers that do not reflect light over a wide range of frequencies. All previous absorbers at other frequencies were either fully reflective, as mirrors, or the range of low reflection was very narrow.img src=»http://feeds.feedburner.com/~r/sciencedaily/~4/oZ_PLMF2UzA» height=»1″ width=»1″ alt=»»/
