Fano resonance in chains of dielectric nanoparticles with side-coupled resonator

In this paper we study the resonant transmission through a waveguide formed by a periodically placed high-index dielectric nanoparticles with a side-coupled resonator. We show that a resonator with high enough Q-factor allows control of the signal transmission through a waveguide. We suggest a practical realization of such scheme that employs a multipole resonance of a dielectric particle with large radius.
