Abstract

A novel design of a dielectric hole plasmonic nanoantenna is proposed and investigated by using a finite element method with three-dimensional calculations. The proposed nanoantenna is composed of two identical hollow nanometal filled dielectric media inside the central part. We examine the influence of the shell thickness, gap width and dielectric media filled inside the hollows on the antenna resonance conditions. Through these simulations, we show that it is possible to tune a plasmonic nanoantenna with a constant length over a broad spectral range.
