Light Pressure of the Bessel Beam on a Spherical Particle: An Analytical Solution

General analytical expressions for the light pressure force acting on a spherical particle placed in the field of the Bessel beam have been derived. It has been shown that an attractive force may arise in the first-order beam if both the dielectric permittivity and magnetic permeability of the particle are positive or negative. For an off-axis particle, it has been found that it may execute eddy motion in the cross-sectional area of the beam, both approaching the axis and moving away from it.
