Proposed experimental setup. The beam coming from an infrared non-polarized laser is split into two by a polarized beam splitter (dark blue). Both beams, s-polarized (crosses) and p-polarized (arrows) are reflected on a mirror (light blue) and focused on the same position of a glass–water interface. Two evanescent waves, TE and TM, with the same intensity and counter-propagating are generated on the water surface, inducing scattering forces on a silicon particle (yellow circle) proportional to Belinfante’s spin momentum and depending on the value of the electric and magnetic dipoles induced on the particle
