Time-reversal inside a granular suspension to probe ultrasound diffusion

Time-reversal inside a granular suspension to probe ultrasound diffusion

We demonstrate that ultrasound diffusion—typically associated with the transport of average wave energy and the breaking of time-reversal symmetry—can nonetheless be revealed through a time-reversal experiment. This is achieved using an unprecedented configuration: A single piezoelectric transducer,...
