SURFACE PLASMON POLARITON LOCALIZATION

Localization of surface plasmons polariton is reviewed in the context of experiments and modeling of near-field optical images. Near-field imaging of elastic (in-plane) surface plasmon scattering is discussed, and approaches for the correct image interpretation are outlined. Nonlinear effects related to localized surface plasmons are pressented. Surface plasmon localization opens up numerous possibilities for application in biosensing, nanophotonics, and in general in the area of surface optics properties.
