Magnetic Light: Optical Magnetism of Dielectric Nanoparticles

Open Access Open Access

Abstract

A split-ring resonator (SRR) is an inductive metallic ring with a gap that can support an oscillating current, giving rise to an optically induced magnetic moment. Unfortunately, metal intrinsic loss sets the limit for using SRRs at optical frequencies. But according to our work, spherical silicon nanoparticles can make an attractive alternative.
