Non-intrusive MEMS microphone sensing of acoustic field state in resonant acoustic levitators
Jan H. Dörsam, Maximilian L. Amberg, Sven Suppelt +6
Reliable operation of resonant acoustic levitators requires knowledge of the acoustic field state because the optimum transducer-reflector distance and resonant operating condition…
