Abstract

ABSTRACTThis article presents an analysis of radiation and absorption properties of cylindrical gold nanodipoles in the transmitting mode. The conventional antenna theory and the linear method of moments are used for theoretical analysis of these antennas in the near‐infrared and lower optical frequencies (100−500 THz). Frequency dependence of radiation and absorption parameters such as input impedance, efficiency, radiation, and loss resistance is calculated for different dipole's lengths and radii. The presented results can be useful to design efficient nanodipoles and to perform the input impedance matching of these antennas with plasmonic optical transmission lines. © 2015 Wiley Periodicals, Inc.
