Study of the excitation of a silver nano dipole

In this paper different excitations of a silver nano dipole in free space are considered. The excitation varieties include a plane wave, and an imposed current with different tuning circuits. The response of the dipole demonstrates a clear resonance response for all excitations. The use of the tuning circuit permits to correct slightly the position of the resonance if necessary. The tuning circuits considered are inspired by the RF domain. They include feeding lines with various widths and different T-match connections. The analysis is performed using a full wave solver based on the method of moments.
