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-based lossless non-reciprocal scattering
Tiemo Pedergnana, Abel Faure-Beaulieu, Romain Fleury +1
Breaking the reciprocity of wave propagation is a problem of fundamental interest, and a mucht-sought functionality in practical applications, both in photonics and phononics. Alth…
