Geometric scaling of the optical memory effect in coherent-wave propagation through random media

Geometric scaling of the optical memory effect is studied for transmission and reflection. Two-dimensional momentum matching, and two-dimensional scaling of the correlation function, is obtained for smooth-surfaced samples from theory and from experiment. Very rough-surfaced samples exhibit three-dimensional scaling. Internal surface reflections are found to play an important role in determining the width of the correlation function, and are shown substantially to account for previous discrepancies between theory and experiment.
