Abstract

The interaction of a radially focused beam with a prolate spheroidal nanoparticle is particularly important because it has the potential to produce strong nearfield electromagnetic radiation. Strong and tightly localized longitudinal components of a radially polarized focused beam can excite strong plasmon modes on elongated nanoparticles such as prolate spheroids. In this study, near field radiation from a prolate spheriodal nanoparticle is investigated when it is illuminated with a radially polarized focused beam of light. Nearfield radiation from the nanoparticle is investigated in the absence and presence of metallic layers.
