Wave propagation and time reversal in the parabolic regime

Wave propagation and time reversal in the parabolic regime Context: time-reversal experiments in ultrasound acoustics. Experimental observations: - robust spatial refocusing - focal spot smaller in random medium than in homogeneous medium Analysis of the mechanisms responsible for statistically stable time reversal. The analysis is based on the semi-classical limit of the Schrodinger equation with a random potential.
