Near-Fields in Assembled Plasmonic Nanostructures

ByP. K. Jain, C. Deeb

Metal nanoparticles exhibit, on account of their localized surface

plasmon oscillations, strong tunable absorption and scattering

resonances and surface-enhanced electric fields. These resonances

and near-fields can be enhanced and engineered further by coupling

metal nanoparticles into defined groupings or assemblies. In this

chapter, we discuss a) the conceptual foundation of plasmonic

coupling between metal nanoparticles, b) how this coupling

influences the near-and far-field optical properties of assembled

metal nanostructures, and c) implications for field-enhanced light-

matter interactions, spectroscopy, nanophotonics, and sensing.
