Abstract

The paper presents a theoretical model for calculating the optical forces caused by the density of spin and orbital momentum and optical torque, caused by the angular momentum typical for a circularly polarized beam or a circular component of an elliptically polarized beam. Total internal reflection at the plate–air interface implemented by the birefringent plate spattered with nanoparticles of gold creates the conditions for the allocation of the predominant action of the vertical spin of the evanescent wave, which has recently been predicted theoretically.
