Paper Abstract

In this work we study optical response of noble metal nanoparticles and report how it may be controllably varied over a wide range of wavelengths. Altering the particle shape and materials we investigate the surface plasmon resonances of nanostars. To design novel nanostructures possessing diverse optical properties we assemble several plasmonic materials into a single nanoparticle. With numerical simulation tool based on the spectral boundary integral equation method we investigate far-field and near-field characteristics of a variety of metal, metal-dielectric and bimetal nanostructures to be used in a range of applications from disease diagnostics through to the identification of contraband.
