  • Abstract
    We report the first evidence of Coherent Backscattering Enhancement for transient elastic waves propagating in a two dimensional chaotic cavity. The intensity at the point source is twice larger than at any other points around the source. Unlike optical experiments, this effect is clearly observable in acoustics on a single realization.
