Plasmonics

Plasmonics or nanoplasmonics refers to the generation, detection, and manipulation of signals at optical frequencies along metal-dielectric interfaces in the nanometer scale. Inspired by photonics, plasmonics follows the trend of miniaturizing optical devices (see also nanophotonics), and finds applications in optical sensing, microscopy, optical communications, and biophotonics.

Magnetoplasmonics is an interdisciplinary field that studies the interactions between magnetism and plasmonics; magnetoplasmonics in confined geometries has the aim to control plasmons through magnetic properties and magnetic phenomena through plasmons.
