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…
Numerical investigation of acoustic solitons
Bruno Lombard, Jean-François Mercier, Olivier Richoux
Acoustic solitons can be obtained by considering the propagation of large amplitude sound waves across a set of Helmholtz resonators. The model proposed by Sugimoto and his coautho…
Transparency robust to disorder in a periodic array of Helmholtz resonators
Olivier Richoux, Agnès Maurel, Vincent Pagneux
In this paper, the influence of disorder on 1D periodic lattice of resonant scatterers is inspected. These later have multiple resonance frequencies which produce bandgap in the tr…
Acoustic solitons in waveguides with Helmholtz resonators: transmission line approach
V. Achilleos, O. Richoux, G. Theocharis +1
We report experimental results and study theoretically soliton formation and propagation in an airfilled acoustic waveguide side loaded with Helmholtz resonators. Our theoretical a…
