Acoustic radiation force on a liquid particle in a standing surface acoustic wave field
Shuo Huang, Hemin Pan, Daniel Ahmed +1
We develop a theory for the acoustic radiation force on a liquid particle in a 2D standing-wave field beyond the Rayleigh limit. The theory is valid for any frequency, includes the…
