Abstract

Light transport through disordered media exhibits various behaviors depending on the disorder strength. Insight is gained on how light interacts with the medium by investigating the statistical properties of the scattering matrix. Historical results were obtained by considering non-resonant scattering systems. In this work, we present innovative numerical results using a microscopic description of systems entirely made out of point-like resonant scatterers. We access light transmission and energy storage in these systems. Their resonant behavior engenders strong frequency-dependent response to incident wavefronts which allows switching between transport regimes while fixing the scatterers density. We show that light can travel ballistically, diffusively or be localized, by only tuning the incident field frequency. The velocity of energy is affected by the resonant behavior of the scatterers, becoming dependent on the disorder strength. Our results suggest benefits in using fully resonant systems for applications aiming at maximal energy deposition within strongly scattering media.
