Researchers demonstrate metasurfaces that control thermal radiation in unprecedented ways

Researchers at the City University of New York have experimentally demonstrated that metasurfaces (two-dimensional materials structured at the nanoscale) can precisely control the optical properties of thermal radiation generated within the metasurface itself. This work paves the way for creating custom light sources with unprecedented capabilities. Metasurfaces offer a solution for greater utility by controlling electromagnetic waves through meticulously engineered shapes of nanopillars that are arrayed across their surfaces.
