METAL-DIELECTRIC NANOCOMPOSITES: NOVEL MATERIALS FOR PLASMONICS

摘要

We report dispersion properties of the surface plasmon polaritons (SPP) in metal-dielectric nanocomposites (MDN). We show that in MDN with a small metal volume fraction the SPP band broadens with an increase in concentration of metal nanoparticles, while in the MDN with a large metal volume fraction, the SPP band splits in two parts.
