Modeling of optical forces in a speckle field

This study examines a model for analyzing the behavior of carbon nanoparticles in speckle field under the influence of optical forces. As a result of computer modeling, optical parameters of carbon nanoparticles were calculated, which made it possible to assess the optical forces (gradient, absorbing and scattering components) acting from internal energy flows in the optical field on carbon nanoparticles. The influence of size of carbon nanoparticles on the ratio of components of optical force is analyzed. Conditions are defined when the amount of gradient force will be significant, which will set the spatial movement of carbon nanoparticles in the area of the minimum, in particular in singular points.
