摘要

我们报道了在二维混沌腔中传播瞬态弹性波的相干后向散射增强的第一个证据。点震源处的强度是震源周围任何其他点的两倍。与光学实验不同，这种效应在声学中可以在单个实现上清楚地观察到。

Coherent backscattering for elastic waves in a chaotic cavity

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.
