The project

We study the multiple scattering of ultrasound by a dense school of fish confined in a large sea farm cage. It turns out that fishes can scatter sound very strongly, allowing one to achieve a scattering mean free path comparable with the wavelength of ultrasound.
The strong scattering allows us to observe such mesoscopic phenomena as the coherent backscattering, field and intensity correlations, fluctuations of the local density of states, etc. and motivates the first objective of this thesis proposal: a study of mesoscopic interference effects in multiple scattering from the wavefield recorded on a 3D ultrasonic array.
