We show that a homogeneous high-index dielectric sphere can exhibit an effective negative permeability. Specifically, we analytically demonstrate that a high-index dielectric can support Mie resonances, where the electromagnetic spatial distributions outside the sphere accurately reproduce the spatial profiles of magnetic localized surface plasmons, generally excited by negative permeability subwavelength particles.

Abstract
We show that a homogeneous high-index dielectric sphere can exhibit an effective negative permeability. Specifically, we analytically demonstrate that a high-index dielectric can support Mie resonances, where the electromagnetic spatial distributions outside the sphere accurately reproduce the spatial profiles of magnetic localized surface plasmons, generally excited by negative permeability subwavelength particles.File in questo prodotto:
