- For the first time, Harvard researchers have created similar wakes of light-like waves moving on a metallic surface, called surface plasmons, and demonstrated that they can be controlled and steered.
- Surface plasmons are confined to the surface of a metal. In order to create wakes through them, Capasso’s team designed a faster-than-light running wave of charge along a one-dimensional metamaterial — like a powerboat speeding across a lake.
- This research addresses a particularly elegant and innovative problem in physics which connects different physical phenomena, from water wakes to sonic booms, and Cherenkov radiation.
