Acoustic vortices provide a single-beam approach to manipulate objects with sizes from
nanometers to millimeters, gaining increasing interest in recent years. The helical beam …

Acoustic radiation force is a net force experienced by an object under the action of an
acoustic wave. Most theoretical models require the acoustic wave to be periodic, if not purely …

Two main methods have been proposed to derive the acoustical radiation force and torque
applied by an arbitrary acoustic field on a particle: The first one relies on the plane wave …

Scattering of an acoustic wave by particles gives rise to microstreaming, as well as to
acoustic radiation and interaction forces on the particles. We numerically study these steady …

The interactions of two Bessel acoustic vortices (BAVs) with different topological charges
(TCs) have been investigated in detail. The theoretical results show that, with changing the …

Holographic acoustical tweezers based on Archimedes-Fermat spiraling interdigitated
transducers (SIDTs) are a versatile tool for the selective manipulation of microparticles …

Selective single beam tweezers open tremendous perspectives in microfluidics and
microbiology for the micromanipulation, assembly, and mechanical properties testing of …

Acoustic manipulations of microparticles have significant implications in physics, chemistry,
biology, and biomedicine. For large Mie particles, both the scattering force and the gradient …

Acoustic orbital angular momentum (OAM) beams hold potential for underwater
communications, particle manipulation, and biomedical applications. However, adapting air …

Acoustic momentum exchange between objects and the surrounding fluid can be quantified
in terms of acoustic radiation force and torque, and depends on several factors including the …
