Mean path length invariance in wave-scattering beyond the diffusive regime

In the diffusive transport regime, the mean path length of waves has been shown to be independent of the microstructure of the medium. Here, this invariance is shown to persist into the ballistic and localized regimes, as well as into the regime of band-gap materials like photonic crystals.
