Near-field mapping of Fano resonances in all-dielectric oligomers

Filonov, Dmitry S.; Slobozhanyuk, Alexey P.; Krasnok, Alexander E.; Belov, Pavel A.; Nenasheva, Elizaveta A.; Hopkins, Ben; Miroshnichenko, Andrey; Kivshar, Yuri


We demonstrate experimentally Fano resonances in all-dielectric oligomers clusters of dielectric particles. We study two structures consisting of a ring of six ceramic spheres with and without a central particle and demonstrate that both structures exhibit resonant suppression of the forward scattering associated with the Fano resonance originated from the excitation of magnetic dipole modes. By employing the near-field measurement techniques, we establish the relation between near- and...[Show more]
