Materials scientists aim to engineer intelligence into the fabric of materials or metamaterials for programmable functions.  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.  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.  Brown University researchers have demonstrated for the first time a method of substantially changing the spatial coherence of light.
