Akselrod: New technology colors in the infrared rainbow


November 30, 2015

In a new study, a team lead by Maiken H. Mikkelsen, the Nortel Networks Assistant Professor of Electrical & Computer Engineering and Physics at Duke University, demonstrates perfect absorbers for small bands of the electromagnetic spectrum from visible light through the near infrared. The fabrication technique is easily scalable, can be applied to any surface geometry and costs much less than current light absorption technologies.

Once adopted, the technique would allow advanced thermal imaging systems to not only be produced faster and cheaper than today’s counterparts, but to have higher sensitivity. It could also be used in a wide variety of other applications, such as masking the heat signatures of objects. The study was published online Nov. 9 in Advanced Materials. Read more.
