Broadband nonreciprocal acoustic propagation using programmable boundary conditions: from analytical modelling to experimental implementation
Sami Karkar, Emanuele De Bono, Manuel Collet +3
In this paper, we theoretically, numerically and experimentally demonstrate the acoustic isolator effect in a 1D waveguide with direction dependent controlled boundary conditions.…
Constant-pressure sound waves in non-Hermitian disordered media
Etienne Rivet, Andre Brandstötter, Konstantinos G. Makris +3
When waves impinge on a disordered material they are back-scattered and form a highly complex interference pattern. Suppressing any such distortions in the free propagation of a wa…
Broadband acoustic isolator in the audible range : nonreciprocal acoustic propagation using programmable boundary conditions
Sami Karkar, Etienne Rivet, Manuel Collet
We propose a novel concept of nonreciprocal devices in acoustics, illustrated by the design of an acoustic diode, or isolator. A boundary control strategy was previously shown to p…
