In this work, the smoothed finite element method using four-node quadrilateral elements
(SFEM-Q4) is employed to resolve underwater acoustic radiation problems. The SFEM-Q4 …

Transducer arrays are a versatile tool for the contactless manipulation of spherical Rayleigh
objects. Here we propose an analytical model for stable levitation of axisymmetric Mie …

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 …

T-matrix methods for electromagnetic structured beams mainly encompass Generalized
Lorenz-Mie Theories (GLMTs) which form a set of analytical approaches dealing with the …

Acoustic radiation force and torque arising from wave scattering are commonly used to
manipulate micro-objects without contact. We applied the partial wave expansion series and …

Acoustic radiation torque (ART) plays an important role in the subject of acoustophoresis,
which could induce the spinning rotation of particles on their own axes. The partial wave …

Acoustic radiation forces (ARFs) induced by a single Bessel beam with arbitrary order and
location on a nonspherical shape are studied using the T-matrix method (TMM) in three …

Apart from a lot of fundamental interest, vector Bessel beams are widely used in optical
manipulation, material processing, and imaging. However, the existing description of such …
