Magneto-optical activity in high index dielectric nanoantennas

N de Sousa, LS Froufe-Pérez, JJ Sáenz… - Scientific reports, 2016 - nature.com
The magneto-optical activity, namely the polarization conversion capabilities of high-index,
non-absorbing, core-shell dielectric nanospheres is theoretically analyzed. We show that, in
analogy with their plasmonic counterparts, the polarization conversion in resonant dielectric
particles is linked to the amount of electromagnetic field probing the magneto-optical
material in the system. However, in strong contrast with plasmon nanoparticles, due to the
peculiar distribution of the internal fields in resonant dielectric spheres, the magneto-optical …
