Experimental characterization of rigid scatterer hyperuniform distributions for audible acoustics
Élie Chéron, Jean-Philippe Groby, Vincent Pagneux +2
Two-dimensional stealthy hyperuniform distributions of rigid scatterers embedded in a waveguide are experimentally characterized the wave transport properties for scalar waves in a…
Underwater metamaterial absorber with impedance-matched composite
Sichao Qu, Nan Gao, Alain Tinel +4
By using a structured tungsten-polyurethane composite that is impedance-matched to water while simultaneously having a much slower longitudinal sound speed, we have theoretically d…
Perfect absorption in mirror-symmetric acoustic metascreens
V. Romero-García, N. Jiménez, J. -P. Groby +5
Mirror-symmetric acoustic metascreens producing perfect absorption independently of the incidence side are theoretically and experimentally reported in this work. The mirror-symmet…
Estimating the material parameters of an inhomogeneous poroelastic plate from ultrasonic measurements in water
Matti Niskanen, Aroune Duclos, Olivier Dazel +3
The estimation of poroelastic material parameters based on ultrasound measurements is considered. The acoustical characterisation of poroelastic materials based on various measurem…
Aerogel-based metasurfaces for perfect acoustic energy absorption
Antonio A. Fernández-Marín, Noé Jiménez, Jean-Philippe Groby +2
The unusual viscoelastic properties of silica aerogel plates are efficiently used to design subwavelength perfect sound absorbers. We theoretically, numerically and experimentally…
Limits of flexural wave absorption by open lossy resonators: reflection and transmission problems
J. Leng, F. Gautier, A. Pelat +3
The limits of flexural wave absorption by open lossy resonators are analytically and numerically reported in this work for both the reflection and transmission problems. An experim…
