Abstract :
In this paper, we investigate the effect of the sub-wavelength spatial phase modulation at the focus of high order paraxial beams on the near-field distribution of plasmonic nanoantennas. We show, in particular, how high-order beams can be used to control the light localization in the gaps of dipolar nanoantennas and in chains of antennas.
