摘要：

We study the intensity angular correlation function of scalar waves, scattered on reflection from disordered media, for the case in which the sample is so small that the speckle pattern does not follow a joint Gaussian statistics, and thus the factorization approximation does not hold. An enhanced long-range correlation is predicted that exhibits two peaks due to coherent effects analogous to those producing the phenomenon of enhanced backscattering of the mean intensity as a result of time-reversal symmetry.
