Researchers from CIC nanoGUNE (San Sebastian, Spain), in collaboration with the Donostia International Physics Center (DIPC, San Sebastian, Spain) and Kansas State University (USA), report in Science the development of a so called 'hyperbolic metasurface' on which light propagates with completely reshaped wafefronts.
This scientific achievement towards a more precise control and monitoring of light is highly interesting for the long run technological challenge of miniaturizing optical devices for sensing and signal processing.
