The invention of tiny devices capable of precisely controlling the direction and behavior of light is essential to the development of advanced technologies. Researchers at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) have taken a significant step forward with the development of a metasurface that can turn invisible infrared light into visible light and aim it in different directions—without any moving parts. The details of their work are explained in a paper published in the journal eLight.
