Acoustic Radiation Force Among Multiple Particles
摘要
The phenomenon of acoustic radiation force is caused by the momentum transfer of incident waves to suspended objects. It can be used to acoustically manipulate particles. Extensive research has been conducted on the acoustic radiation force applied to individual objects in previous theories and experiments. However, in practical operations, several suspended particles may appear in an external sound field simultaneously. When multiple particles exist in the sound field, on one hand, these particles will interact with the sound field; on the other hand, there will be interactions between the particles themselves. The scattering field emerging from one particle will cause further scattering from the surrounding particles.
