Theory on Manipulation of Rayleigh Particles in New Elliptical Vector Hollow Beams
A scheme for asymmetric manipulation of Rayleigh particles using elliptical vector hollow beams is presented. The scattering force and the gradient force of the elliptical vector hollow beams on the Rayleigh particle which are in these beams are theoretically calculated. Taking the elliptical vector hollow beams produced in the experiment as the manipulating beams, and taking the water molecules group in acetyl benzene liquid as the research object, the theoretical analysis of the trapping dynamics of the related particles is carried out, and the Monte-Carlo method is used to simulate the trapping dynamics. The theoretical research results show that the scattering force onto the Rayleigh particles in elliptical vector hollow beams is much smaller than that of the gradient forces. The Rayleigh particle can be trapped in the asymmetrical hollow part of the beam by choosing the appropriate light intensity.
