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.
