Abstract:
The angle-and-displacement relationship of the orbital angular moment of force acting by a non-paraxial cylindrical Gaussian beam on a cylindrical microparticle with the complex refractive index is numerically studied. It is shown that the moment of force acting on an absorbing particle with an elliptical cross-section with respect to the center of the particle located at the center of a Gaussian beam waist is much less than the moment acting on a non-absorbing particle for the same parameters, and the absorbing particle with a circular cross-section rotates if its center is shifted from an optical axis.

Key words:
moment of light force, cylindrical microparticle, Gaussian beam.
