Numerical Analysis of Different Nanoantennas in Reception Mode for Application in Optical Nanocircuits

Abstract

In this work, a study is made comparing different cases of optical nanoantennas in the reception mode. The nanoantennas considered are: dipole, dipole-loop, isolated loop and nanorod-loop, excited by a plane wave. The numerical analysis is performed by the Finite Element Method (FEM), where the received power by the load versus frequency is investigated for these four cases, results show better power reception is close to the resonant frequency for each case. It is also presented the analysis of an optical nanocircuit, which is composed by a receiving loop nanoantenna connected to a bifilar optical transmission line (OTL) in one side, and a dipole in the other side. In this case, a plane wave is the source and the near field is investigated.
