Acoustic transparency and absorption in dense granular suspensions
Arnaud Tourin, Yamil Abraham, Marie Palla +5
We demonstrate the existence of a frequency band exhibiting acoustic transparency in 2D and 3D dense granular suspensions, enabling the transmission of a low-frequency ballistic wa…

Time-Reversal Mirror inside a granular suspension: a way of measuring the ultrasound diffusion coefficient
Y. Abraham, B. A. van Tiggelen, N. Benech +3
We demonstrate that the diffusion coefficient, , for ultrasound propagating in a multiple scattering medium, such as a dense granular suspension, can be measured using a time re…
