Spectral behavior of localized plasmon resonances in the near- and far-field regimes. Comment on The spectral shift between near- and far-field resonances of optical nano-antennas

Fernando Moreno, Pablo Albella, Manuel Nieto-Vesperinas

In a recent paper by Menzel et al. (Opt. Exp. 22, 9971 (2014)), its authors analyze the spectral red-shift effect of plasmonic resonances of metallic nano-antennas between the far-…
