This book provides a comprehensive overview of the acoustic radiation force on spherical particles. It explores the force exerted by Gaussian traveling waves and spherically focused ultrasound using the ray acoustics method. The book also discusses the force generated by plane waves and Gaussian traveling waves, using the acoustic scattering method. Additionally, it examines the effects of Gaussian standing waves and multi-layered spherical particles. Beyond these core topics, the book covers the acoustic radiation force from other sound sources. These include beams produced by hollow focused transducers and annular piston transducers, as well as zero-order quasi-Bessel Gaussian beams and Airy-Gauss beams. It also explains how boundaries impact the acoustic radiation force and the interactions between multiple particles. Finally, the book highlights the medical applications of acoustic radiation force. By covering these diverse aspects, the book inspires more in-depth and comprehensive research into using acoustic radiation force to manipulate particles. The book is suitable for upper undergraduate students and graduate students in acoustics, as well as researchers and professionals engaged in the study of ultrasound and medical imaging.
