Control of acoustic absorption in 1D scattering by indirect coupled resonant scatterers
A. Merkel, G. Theocharis, O. Richoux +2
We experimentally report perfect acoustic absorption through the interplay of the inherent losses and transparent modes with high factor. These modes are generated in a two-por…
Invariant currents in lossy acoustic waveguides with complete local symmetry
P. A. Kalozoumis, O. Richoux, F. K. Diakonos +2
We implement the concept of complete local symmetry in lossy acoustic waveguides. Despite the presence of losses, the existence of a spatially invariant current is shown theoretica…
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.…
