Phys.org December 13, 2022 Understanding the acoustic scattering and radiation force and torque of an object is important in various fields, such as underwater communication, acoustic imaging, and noninvasive characterization, as well as biomedical ultrasound. An international team of researchers (Saudi Arabia, UK, USA – University of Illinois) studied scattering off cylindrical objects in spinning motion around the axis of rotational symmetry to investigate the radiation force and torque induced by various incident signals, e.g., cylindrical diverging and converging beams as well as quasi-Gaussian beams of different orders. The study assumed that the acoustic parameters of the objects (density and […]
