Light scattering by subwavelength Cu₂O particles

Abstract

Novel metamaterials with new capabilities to manipulate light may be performed by considering basic building blocks with new optical properties. This is the case of resonant magneto-dielectric particles. In this work, the resonant response of high-dielectric Cu2O subwavelength particle is analyzed, both analytically and experimentally. The emergence of electric and magnetic resonances and their interferential effects, producing directional behaviors, can be used in a new generation of metamaterials, as well as new integrated optical devices.
