Paper Abstract
We report mapping of the lateral magnetic near-field distribution of plasmonic resonant modes in different nanostructure geometries by hollow-pyramid probe aperture-SNOM. Using full-field simulations we investigate how the near-field probe acts as a confined light source and how it efficiently excites surface plasmons. This excitation occurs at lateral magnetic field maxima, enabling the visualization of the lateral magnetic near-field distribution with subwavelength spatial resolution. Our approach complements the available methods for imaging the different field components of light.
