Transverse and Lateral Shifts of the Centre of Gravity of a Nonparaxial Bessel Beam Propagating Perpendicularly to a Refractive Index Gradient
(English)Article in journal (Refereed) Submitted
By applying geometrical optics (GO) to each plane wave component of a nonparaxial electromagnetic (e-m) Bessel beam carrying spin and orbital angular momentum (SAM/OAM), we calculate the shift of the beam centroid during propagation perpendicular to the refractive index gradient in an isotropic medium. In addition to the transverse spin and orbital Hall shifts expected from paraxial theory, the nonparaxial treatment reveals new shifts in both the transverse and lateral directions.
