ABSTRACT
Nanoplasmonics is a component of nano-optics, which is optics
at the nanometer scale. The subject of nanoplasmonics is optical
properties of metal nanoparticles and nanostructures determined
by conduction electron oscillations around a crystal lattice. Primari-
ly, importance of nanoplasmonics is based on two factors. First,
localization and enhancement of optical fields can occur due to
the presence of a spatial nanoscale substance (the lightning rod
effect). Second, frequencies of metal nanoparticle eigenoscillations
are located in the optical spectrum in ranges from ultraviolet to
infrared. Coexistence of these two properties of metal nanoparticles
causes an interesting and complex physics, which forms the basis for
numerous applications.
