Distortion matrix approach for ultrasound imaging of random scattering media
William Lambert, Laura A. Cobus, Thomas Frappart +2
Focusing waves inside inhomogeneous media is a fundamental problem for imaging. Spatial variations of wave velocity can strongly distort propagating wavefronts and degrade image qu…

Reflection matrix approach for quantitative imaging of scattering media
William Lambert, Laura A. Cobus, Mathieu Couade +2
We present a physically intuitive matrix approach for wave imaging and characterization in scattering media. The experimental proof-of-concept is performed with ultrasonic waves, b…

Transverse confinement of ultrasound through the Anderson transition in 3D mesoglasses
L. A. Cobus, W. K. Hildebrand, S. E. Skipetrov +2
We report an in-depth investigation of the Anderson localization transition for classical waves in three dimensions (3D). Experimentally, we observe clear signatures of Anderson lo…
