Optical manipulations utilizing the mechanical effect of light have been indispensable in
various disciplines. Among those various manipulations, optical pulling has emerged …

Optical forces is a unique phenomenon derived from light–matter interaction. It took
centuries before people were finally able to measure, and manipulate this extremely tiny …

We present a unified and extended perspective of Bessel beams, irrespective of their orbital
angular momentum (OAM)—zero, integer or noninteger—and mode—scalar or vectorial …

Optical tractor beams, proposed in 2011 and experimentally demonstrated soon after, offer
the ability to pull particles against light propagation. It has attracted much research and …

Recently, VV Kotlyar et al.[Opt. Lett. 39, 2395 (2014)] have theoretically proposed a novel
kind of three-parameter diffraction-free beam with a crescent profile, namely, the asymmetric …

This paper presents two key contributions; the first concerns the development of analytical
expressions for the axial and transverse acoustic radiation forces exerted on a 2D rigid …

The Airy acoustical beam exhibits parabolic propagation and spatial acceleration, meaning
that the propagation bending angle continuously increases before the beam trajectory …

The acoustic radiation force on a 2D elliptical (non-circular) cylinder centered on the axis of
wave propagation of plane quasi-standing and standing waves is derived, based on the …

A formal theoretical analysis is developed using the partial-wave series expansion (PWSE)
method in spherical coordinates, which allows accurate evaluation of the acoustic radiation …

We provide a detailed analysis on the acoustic radiation force and torque exerted on a
homogeneous viscoelastic particle in the long-wave limit (ie the particle radius is much …
