The investigation of the peculiarities of the motion of testing nanoobjects in the inhomogeneously-polarized optical field

Abstract

The paper proposes for consideration an additional possibility to evaluate the degree of coherence of superposing mutually orthogonal linearly-polarized in the incidence plane waves. When analyzing the behavior of various-type particles (Mie and Rayleigh) in the inhomogeneously polarized optical field and in the inhomogeneous field of the averaged values of the Poynting vector, we obtain an additional tool for defining the degree of coherence of interacting fields. The spatial modulation of polarization in the observation plane shapes the spatial modulation of the energy density volume, which changes the velocity of the particle motion according to the coherence characteristics of the superposing fields and to the resulting optical force that causes the motion and trapping of the tested particles.
