With the fascinating progress in theoretical studies and successful implementations of modern microfabrication techniques, the recent extensive research on surface plasmons in metallic nanostructures has merged into a new rapidly growing discipline, called plasmonies. Due to the unique optical properties associated with surface plasmons, plasmonics, which could find wide useful applications in data storage, diffraction-suppressed imaging, light beam collimation, solar cells, biosensors, negative refraction etc, is now one of the most active research fields in the world. Here we review the current status of surface plasmons, including their basic features, novel effects, and potential applications.
