Abstract:
In the geometric optics approximation, we comparatively analyze the polarization
effects resulting from the influence of polarization on the beam
trajectory. We show that the beam trajectory equations describing the optical
Magnus effect that are obtained from the canonical Hamilton equations, Fermat
principle, and truncated vector wave equations give the same result,
coincident with the result in the mode approach. We explain the reasons
underlying the previously derived results.
Keywords:optical Magnus effect, circular polarization, Fermat principle, Poynting vector.
