On the basis of the wave equation of a vibrating beam, the impact of an elastic body on the beam is studied, mad the contact forces, strains, and stresses arc determined. The results are compared with the calculations carried out for the nonwave equation. It is shown that, for relatively...
The radiation force of highly focused elliptically polarized beams on a Rayleigh particle is theoretically studied. The numerical results show that elliptically polarized beams can be used to trap particles. The influence of the beam widths, phase retardations of the incident beam, and numerical ...

A large number of studies have been devoted to this technique, but most of them assume that the particle under study is a homogeneous particle. Here we focus our attention on radiation pressure forces and torques exerted by a Gaussian beam on a multilayered sphere, with a particular attention...
We calculate the forces of single-beam gradient radiation pressure laser traps, also called “optical tweezers,” on micron-sized dielectric spheres in the ray optics regime. This serves as a simple model system for describing laser trapping and manipulation of living cells and organelles within ...
