On the contribution of circumferential resonance modes in acoustic radiation force experienced by cylindrical shells

摘要: Abstract A body insonified by a constant (time-varying) intensity sound field is known to experience steady (oscillatory) force that called the steady-state (dynamic) acoustic radiation force. Using classical resonance scattering theorem (RST) which suggests scattered as superposition of and background (non-resonance) component, we show acting on cylindrical shell may be synthesized composition three components: part, part their interaction. The component reveals pure geometrical reflection effects illustrates regular behavior with respect frequency, while others demonstrate singular near frequencies. results illustrate associated partial waves can isolated subtraction from total (steady-state or dynamic) function (i.e., residue component). In case force, components are exerted static forces. For oscillatory amplitude excitation, at modulation frequency frequency-dependant phase shifts. dominant contribution non-resonance dynamic high frequencies offers potential application ultrasound stimulated vibro-acoustic spectroscopy technique in low purposes. Furthermore, proposed formulation useful essentially due its intrinsic value physical acoustics. addition, it unveil modes experienced objects underlying physics.
