Abstract
We demonstrate amplitude- and phase-resolved near-field mapping of nanoantennas by scattering-type near-field optical microscopy. The technique is applied to monitor the evolution of the near-field oscillations of infrared gap antennas progressively loaded with metallic bridges of varying size. Our results provide direct experimental evidence that nanoscale infrared near fields can be controlled by antenna loading, which is in excellent agreement with numerical calculations.
