Surface plasmon-polaritons are electromagnetic modes where electromagnetic waves are coupled to the surface electrons of a metal/dielectric interface. These electromagnetic modes attracted a lot of attention over the last decade as they provide the key to overcome the diffraction limit of light: Light can not be squeezed to a spot smaller than half its wavelength. In contrast, plasmonic modes are capable of squeezing light to spaces smaller than light diffraction limit.

The science of plasmonics study the interaction of light with nanoscale structures that support surface plasmon oscillation.
