Abstract

A team of scientists in France has created a metasurface on which individual plasmonic nanoantennas act as infrared “pixels,” allowing the surface to encode infrared images of surprising detail. The fabrication technique can encode multiple images on a single metasurface that can be read out by using different settings of polarization and wavelength—a characteristic that the researchers believe could make the metasurfaces useful in applications such as anti-counterfeit devices.
