摘要:

A comparison of differently polarized Bessel vortex beams propagating through a uniaxial anisotropic slab is discussed in terms of the vector wave function expansions. The magnitude profiles of electric field components, the transformation of polarization modes, and the distributions of orbital angular momentum (OAM) states of the reflected and transmitted beams for different incident angles are numerically simulated. The results indicate that the magnitude profiles of electric field components for different polarization modes are distinct from each other and have a great dependence on the incident angle, thus the transformation of polarization modes which reflects the change of energy can be affected largely. As compared to the x and circular polarization incidences, the reflected and transmitted beams for the radial polarization incidence suffer the fewest transformation of polarization modes, showing a better energy invariance. The distributions of OAM states of the reflected and transmitted beams for different polarization modes are diverse as well, and the derived OAM states of the transmitted beam for radial polarization present a focusing effect, concentrating on the state between two predominant OAM states.
