Harnessing Geometric Frustration to Form Band Gaps in Acoustic Channel Lattices
Pai Wang, Yue Zheng, Matheus C. Fernandes +6
We demonstrate both numerically and experimentally that geometric frustration in two-dimensional periodic acoustic networks consisting of arrays of narrow air channels can be harne…
Asymmetric acoustic propagation of wave packets via the self-demodulation effect
Thibaut Devaux, Vincent Tournat, Olivier Richoux +1
This article presents the experimental characterization of nonreciprocal elastic wave transmission in a single-mode elastic waveguide. This asymmetric system is obtained by couplin…
Nonlinear Hysteretic Torsional Waves
J. Cabaret, P. Béquin, G. Theocharis +3
We theoretically study and experimentally report the propagation of nonlinear hysteretic torsional pulses in a vertical granular chain made of cm-scale, self-hanged magnetic beads.…
Perfect and broadband acoustic absorption by critical coupling
V. Romero-García, G. Theocharis, O. Richoux +3
We experimentally and analytically report broadband and narrowband perfect absorption in two different acoustic waveguide-resonator geometries by the mechanism of critical coupling…
Using simple shape three-dimensional inclusions to enhance porous layer absorption
Jean-Philippe Groby, Benoit Nennig, Clément Lagarrigue +3
The absorption properties of a metaporous material made of non-resonant simple shape three-dimensional inclusions (cube, cylinder, sphere, cone and torus) embedded in a rigidly bac…
Nonlinear effects for coda-type elastic waves in stressed granular media
Vincent Tournat, Vitalyi Gusev
Experimental results and their interpretations are presented on the nonlinear acoustic effects of multiple scattered elastic waves in unconsolidated granular media. Short wave pack…
Acoustic Probing of the Jamming Transition in an Unconsolidated Granular Medium
Xavier Jacob, Vladislav Aleshin, Vincent Tournat +3
Experiments with acoustic waves guided along the mechanically free surface of an unconsolidated granular packed structure provide information on the elasticity of granular media at…
