Abstract

In the previous chapter we have shown that the lateral magnetic near-field distributions of different resonant modes in plasmonic structures can be mapped with a hollow-pyramid aperture SNOM. We have also discussed how the coupling between the probe and the metal bars leads to the obtained results. This chapter focuses on the underlying mechanism for mapping the lateral magnetic field with this circular aperture type probe. We suggest that such probe can be approximated by a lateral magnetic dipole source, which also allows its use as a detector for the lateral magnetic near-field. The equivalence of the reciprocal configurations when the probe is used as a source (illumination mode) and as a detector (collection mode) is experimentally demonstrated for a plasmonic nanobar sample. Verification for dielectric structures remains to be realized. The simplification of the probe to a simple magnetic dipole is extremely useful from a practical point of view, as it facilitates the simulations and the understanding of the near-field images.
