Simulating and Measuring the Acoustic Radiation Force of a Focused Ultrasonic Beam on Elastic Spheres in Water

  • Published:
Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

The phenomenon of acoustic radiation force acting on solid spherical scatterers inside the field of a focused ultrasonic beam is experimentally studied. Nylon and glass beads are used as scatterers; the acoustic field is generated by a piezoceramic transducer of the megahertz frequency range in water. The angular spectrum of the ultrasonic beam, obtained from the measured transverse distribution of the amplitude and phase of the acoustic pressure, is used to calculate the theoretical value of the radiation force. The results from these calculations are in agreement with the experimentally determined value of the radiation force.
