Metamaterials Reprogram Themselves

Authors: George Rajna

Materials scientists aim to engineer intelligence into the fabric of materials or metamaterials for programmable functions. [15] Researchers at Aalto University have developed new metasurfaces for the arbitrary manipulation of reflected waves, essentially breaking the law to engineer the reflection of a surface at will. [14] In new research, scientists at the University of Minnesota used a first-of-its-kind device to demonstrate a way to control the direction of the photocurrent without deploying an electric voltage. [13] Brown University researchers have demonstrated for the first time a method of substantially changing the spatial coherence of light. [12]
