Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201570207-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>On page 4597, A. Tittl and co‐workers present a switchable perfect absorber with multispectral thermal imaging capability. Aluminum nanoantenna arrays above a germanium antimony telluride spacer layer and an aluminum mirror are utilized to achieve efficient and wavelength‐tunable absorption in the mid‐infrared. The image by A. Tittl and D. Floess shows an artist's view of how such switchable absorber layers can be incorporated into a pixelated microbolometer array for band‐selective thermal‐imaging applications. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgj2f6z091g" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
