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.…
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…
Oscillation threshold of a clarinet model: a numerical continuation approach
Sami Karkar, Christophe Vergez, Bruno Cochelin
This paper focuses on the oscillation threshold of single reed instruments. Several characteristics such as blowing pressure at threshold, regime selection, and playing frequency a…
A high order purely frequency-based harmonic balance formulation for continuation of periodic solutions
Bruno Cochelin, Christophe Vergez
Combinig the harmonic balance method (HBM) and a continuation method is a well-known technique to follow the periodic solutions of dynamical systems when a control parameter is var…
