Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

A rainbow reveals with colors what otherwise remains hidden: light is "refracted" by transparent matter, in this case water ...

From ultrafast photodetectors to multifunctional flat lenses, metasurfaces are redefining how we manipulate light. These nanostructured surfaces pack powerful optical functions into ultra-thin forms, ...
