The paper presents main theoretical approaches allowing for calculation of optical force and torque in a birefringent medium under the condition of total internal reflection realization. Evanescent wave realized under the plate is elliptically polarized, possesses spin angular momentum and is a cause of object motion. In this case linearly polarized incident wave with the azimuth of polarization of ±45° forms vertical spin, which determines the transversal motion of the object and it is demonstrated in the given paper. The obtained results will be of vital importance in numerous areas where one operates with minute quantities of matter such as nanophysics, nanophotonics, precise chemistry and pharmacology etc.
