Airborne Minnaert-Like Resonance of an Air-Filled Elasto-Bubble
Fanambinana Delmotte, Valentin Leroy, Jishen Zhang
Deep-subwavelength acoustic resonators are key building blocks of acoustic metamaterials, yet achieving bubble-like resonances in air remains challenging because the Minnaert mecha…
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…
Ultrasound transmission through monodisperse 2D microfoams
Lorène Champougny, Juliette Pierre, Antoine Devulder +2
While the acoustic properties of solid foams have been abundantly characterized, sound propagation in liquid foams remains poorly understood. Recent studies have investigated the t…
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…
An FFT approach to the analysis of dynamic properties of gas/liquid interfaces
Sandrine Mariot, Valentin Leroy, Juliette Pierre +4
The characterisation of the dynamic properties of viscoelastic monolayers of surfactants at the gasliquid interface is very important in the analysis and prediction of foam stabili…
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…
Manipulating bubbles with secondary Bjerknes forces
Maxime Lanoy, Caroline Derec, Arnaud Tourin +1
Gas bubbles in a sound field are submitted to a radiative force, known as the secondary Bjerknes force. We propose an original experimental setup that allows us to investigate in d…
Enhanced and reduced transmission of acoustic waves with bubble meta-screens
Alice Bretagne, Arnaud Tourin, V. Leroy
We present a class of sonic meta-screens for manipulating air-borne acoustic waves at ultrasonic or audible frequencies. Our screens consist of periodic arrangements of air bubbles…
Influence of positional correlations on the propagation of waves in a complex medium with polydisperse resonant scatterers
V. Leroy, A. L. Strybulevych, J. H. Page +1
We present experimental results on a model system for studying wave propagation in a complex medium exhibiting low frequency resonances. These experiments enable us to investigate…
