Wide-band Nanoantenna for Optical and Infrared Energy Harvesting

Abstract

In this paper, a novel design of Logarithmic Spiral Nanoantenna is introduced and numerically analyzed for energy harvesting applications. The proposed design consists of two arms spiral nanoantenna placed on a glass substrate. Full systematic analysis is carried out where the antenna impedance, return loss, field confinement are calculated using FDTD. In addition, studies show the power absorption of the antenna to calculate its harvesting capability.
