Dual and anti-dual modes in dielectric spheres

Opt Express. 2013 Jul 29;21(15):17520-30. doi: 10.1364/OE.21.017520.

Abstract

We present how the angular momentum of light can play an important role to induce a dual or anti-dual behaviour on a dielectric particle. Although the material the particle is made of is not dual, i.e. a dielectric does not interact with an electrical field in the same way as it does with a magnetic one, a spherical particle can behave as a dual system when the correct excitation beam is chosen. We study the conditions under which this dual or anti-dual behaviour can be induced.
