title: Delocalization of classical waves in highly anisotropic random media.
abstract: We discuss localization phenomena in multilayer films doped with scattering particles. If the films exhibit a particular type of transmission resonance then above a critical frequency waves in the sample can decay as a power law rather than exponentially. This phenomenon is independent of the scattering strength of the particles, in stark contrast to previous work. We find that this phenomenon has many similarities to a second order phase transition. This work points to interesting avenues in the study of waves in anisotropic disordered media.
