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…
Symmetry violation-driven hysteresis loops as measurands for noise-resilient sensors
Arunn Suntharalingam, Lucas Fernández-Alcázar, Pablo Fabián Wagner-Boián +3
Sublinear resonant deviations from an exceptional point degeneracy (EPD) has been recently promoted as a sensing scheme. However, there is still an ongoing debate whether the sensi…
Optimal Targeted Mode Transport in Complex Wave Environments: A Universal Statistical Framework
Cheng-Zhen Wang, John Guillamon, Ulrich Kuhl +4
Recent advances in the field of structured waves have resulted in sophisticated coherent wavefront shaping schemes that provide unprecedented control of waves in various complex se…
