Abstract

A highly tunable optical nanoantenna element is proposed through gradual transformation from a sphere to a prolate spheroid. This new element induces field enhancement and an increase in resonance frequency. Rather than a purely metallic material, we propose the use of a metal-coated dielectric spheroid as a nanoelement because of its flexibility. We show that a spheroidal element enhances the near-field better than its rod and sphere counterparts. As such, spheroidal elements are good candidates for improving solar-cell performance.
