Three-dimensional acoustic lensing with a bubbly diamond metamaterial
Maxime Lanoy, Fabrice Lemoult, Geoffroy Lerosey +3
A sound wave travelling in water is scattered by a periodic assembly of air bubbles. The local structure matters even in the low frequency regime. If the bubbles are arranged in a…
Ultrasonic tracking of a sinking ball in a vibrated dense granular suspension
S. van den Wildenberg, X. Jia, J. Léopoldès +1
Observing and understanding the movement of an intruder through opaque dense suspensions such as quicksand remains a practical and conceptual challenge. Here we use an ultrasonic p…
Drastic slowdown of shear waves in unjammed granular suspensions
J. Brum, J. -L. Gennisson, M. Fink +2
We present an experimental investigation of shear elastic wave propagation along the surface of a dense granular suspension. Using an ultrafast ultrasound scanner, we monitor the s…
Acoustic double negativity induced by position correlations within a disordered set of monopolar resonators
Maxime Lanoy, John H. Page, Geoffroy Lerosey +3
Using a Multiple Scattering Theory algorithm, we investigate numerically the transmission of ultrasonic waves through a disordered locally resonant metamaterial containing only mon…
Time reversal of ultrasound in granular media
Maxime Harazi, Yougu Yang, Mathias Fink +2
Time reversal (TR) focusing of ultrasound in granular packings is experimentally investigated. Pulsed elastic waves transmitted from a compressional or shear transducer source are…
Time reversal sub-wavelength focusing in bubbly media
Maxime Lanoy, Romain Pierrat, Fabrice Lemoult +3
Thanks to a Multiple Scattering Theory algorithm, we present a way to focus energy at the deep subwavelength scale, from the far-field, inside a cubic disordered bubble cloud by us…
