All-dielectric “magnetic light” nanophotonics based on high refractive index nanoparticles
allows controlling magnetic component of light at nanoscale without having high dissipative
losses. The artificial magnetic optical response of such nanoparticles originates from circular
displacement currents excited inside those structures and strongly depends on geometry
and dispersion of optical materials. Here an approach for enhancing of magnetic response
via resonant bianisotropy effect is proposed and analyzed. The key mechanism of …
