Abstract :
We present a technique based on full-field heterodyne holography for the mapping of the scattered field of plasmonic gold nanoantennas in all three dimensions. A spectroscopic study allowed us to determine resonant and non-resonant wavelengths at which we conducted a full characterization of the scattered field for different polarizations and for a wide range of antennas. These results are compared to numerical simulations.
