Abstract
We report the first measurements of dynamic transport properties of an acoustic pulsed wave propagating in a strongly disordered 2D medium by means of time-dependent coherent backscattering. The coherent backscattering peaks are recorded using an array of transducers. Both transport speed and diffusion coefficient have been determined accurately by comparison to a real-space generalization of coherent backscattering in optics.Keywords
