We reveal unusually strong polarization sensitivity of electric and magnetic dipole resonances of high-index dielectric nanoparticles placed on a metallic film. By employing dark-field spectroscopy, we observe the polarization-controlled transformation from high-Q magnetic-dipole scattering to broadband suppression of scattering associated with the electric dipole mode, and show numerically that it is accompanied by a strong enhancement of the respective fields by the nanoparticle....[Show more]
