Abstract

In this work, while exploiting the latest multiple scattering software that can handle up to a million of particles, we explore the possibility to observe Anderson localization of light in a disordered medium. The proposed method is an excellent tool to manipulate the multipolar response from the spheres such that regimes can be identified where light localization happens. Moreover, by calculating the mean free path in the cluster via simulation data, the localization wavelengths can be now effectively pinpointed. Both features could provide clear guidelines for future optical transmission experiments and for designs utilizing Anderson localization of light.
