Paper Abstract

Analytical theory and numerical calculations for periodic arrays of metal nanoparticles indicate resonant-like enhancement of local electromagnetic field, which can be tuned by varying a ratio of particle diameter to interparticle spacing. For Raman scattering, local field enhancements on the order of 1013 and surface-averaged field enhancements on the order of 1011 can be achieved udner optimal conditions. This is several orders of magnitude greater tan that obtaiend in disordered metal-dielectric films, and suggests a new design for engineering plasmonic substrates supporting intense and spatially well-defined field patterns, with direct applications for surface-enhanced Raman scattering (SERS), and surface-enhanced optical nonlinearities.
