Synchronization driven acoustics: The nonlinear scattering of a self-oscillating meta-atom
Alexander K. Stoychev, Xinxin Guo, Ulrich Kuhl +1
In this study we demonstrate a self-oscillating acoustic meta-atom functioning as an amplifying transistor, where a steady external flow serves as a control signal to switch betwee…

Synchronization driven reciprocity breaking
Alexander K. Stoychev, Ulrich Kuhl, Nicolas Noiray
This study introduces a novel method to break wave transmission reciprocity by leveraging the synchronization of self-oscillators. An experimental demonstration with aeroacoustic c…
