Entrainment and stimulated emission of auto-oscillators in an acoustic cavity
Richard L Weaver, Oleg I Lobkis, Alexey Yamilov
We report theory, measurements and numerical simulations on nonlinear piezoelectric ultrasonic devices with stable limit cycles. The devices are shown to exhibit behavior familiar…
