Light Pressure on a Spherical Particle in the Interference Field of Two Monochromatic Bessel Beams

General analytical expressions are derived for the light pressure force that acts on a spherical particle of arbitrary size and material composition (dielectric, metal) located in the interference field of two arbitrary monochromatic vector Bessel beams. For identical beams on orders of m = 0 and 1, the light pressure force is examined for the case of two parallel and copropagating beams and the case of intersection of the beam axes near a dielectric particle. It is shown that the presence of interference leads to a complex motion of a particle located in a plane perpendicular to the parallel beams. It is also demonstrated that with a change in the angle formed by the intersection of the axes of Bessel beams in the center of the particle, the light pressure force changes nonmonotonically, passing through maxima and minima, the number of which increases with increasing particle size. When the particle is displaced from the intersection point of the axes along a straight line located symmetrically between the beams, the light pressure force oscillates with a change in sign and with a gradually decreasing amplitude.
