In this paper, systematic study for asymmetric tapered dipole nanoantenna is implemented using finite element frequency domain (FEFD) solver where harvesting efficiency, field confinement, surface current, and input impedance are calculated at wavelength of 500 nm. The proposed nanoantennas achieve a harvesting efficiency of 61.3% and a field enhancement factor of 37.7 over the conventional dipole...
In this paper, a novel design of Yagi–Uda nanoantenna is introduced and numerically analyzed using finite integration technique via computer simulation technology software. The proposed nanoantenna consists of five core-shell nanowires with silicon cladding and silver core to achieve high directivity for wireless point to point applications. The proposed design shows a high directivity of 17.21 at...
In this paper, two novel designs of nanoantenna for energy harvesting applications are introduced and numerically simulated using the 3D FDTD method. The proposed designs are mainly based on generating identical copies of original elliptical dipoles and then shifting the copies horizontally or vertically. The original elliptical dipoles and the shifted copies are merged together to obtain two novel...
