Interplay of Magnetic Responses in All-Dielectric Oligomers to Realize Magnetic Fano Resonances

Hopkins, Ben; Filonov, Dmitry; Monticone, Francesco; Alu, Andrea; Miroshnichenko, Andrey; Kivshar, Yuri


We study the interplay between collective and individual optically induced magnetic responses in quadrumers made of identical dielectric nanoparticles. Unlike their plasmonic counterparts, all-dielectric nanoparticle clusters are shown to exhibit multiple dimensions of resonant magnetic responses that can be employed for the realization of anomalous scattering signatures. We focus our analysis on symmetric quadrumers made from silicon nanoparticles and verify our theoretical results in...[Show more]
