Surface plasmons are density waves of electrons—picture bunches of electrons passing a point regularly—along the surface of a metal. Plasmons have the same frequencies and electromagnetic fields as light, but their sub-wavelength size means they take up less space. Plasmonics, then, is the technology of transmitting these light-like waves along nanoscale wires.
The research is a prime example of work at the forefront of two strategic initiatives of the School of Engineering: information technology and photonics, and nanoscience and nanotechnology.
