Design, Simulation, Characterization and Analysis of Electromagnetic Energy Harvesting Devices

Abstract

In this chapter, a novel flower-shaped dipole nano-antenna for energy harvesting is presented and analyzed using an accurate 3D-FDTD method. The proposed flower-shapeddesign is found to exhibit higher efficiency over the conventional dipole antenna by at least 15%. In addition, the totalharvesting efficiency is enhanced by 32.7%. Moreover,the suggested nanoantenna offers a large bandwidth in thewavelength range from 450 to 1400 nm. Additionally, theflower-shaped dipole nanoantenna has better efficiencyof 74.6% compared with the conventional solar cells atλ = 500 nm at which the sun irradiance is maximum. The obtained results pave the road to higher efficiencies in transforming light into electrical energy through such designs.
