Abstract
Fano resonance combs are characteristic of Rydberg autoionizing states and have recently been observed in Mie scattering by water droplets. We demonstrate the generality of this effect by revealing overlapping combs of Fano resonance in the extinction spectra of dielectric resonators using rings and split rings with rectangular cross sections as examples. An unambiguous interpretation of the series of overlapping Fano resonance combs is obtained using quasinormal mode theory.
