Yet another output of our fruitful collaboration - this paper will be useful for anyone performing near-field experiments on dielectric resonators near conductive surfaces, in particular, in experiments using aperture probes. We explain the polarity of the Fano-profiles observed in the near-field electric field spectra recorded at frequencies close to the frequencies of magnetic dipole resonances of dielectric resonators.
Summary: Fano resonances are observed in the near‐field electric‐field spectra of dielectric particles sustaining magnetic multipole resonances and located near a conductive surface (reflector). This paper proves, theoretically and experimentally, that these Fano resonances originate from the particles' interaction with the standing wave formed near the reflector; and that their polarity is defined by the relative positions of the resonant particle, the observation points, and the reflector.
