antenna-like nanorods (IMAGE) Penn State Caption Researchers fabricated an optical element that uses a forest of tiny, antenna-like nanorods, seen here, that together create a metamaterial able to control the spin of light. The metamaterial nanorods appear to be shaped like the letter “L” when seen at the nanoscale. Credit Provided by Christos Argyopoulos Usage Restrictions Credit must be given to the creator.
