Formation of radially and azimuthally polarized Bessel light beams at interaction with layered periodic anisotropic media

摘要

A new method of formation of radially and azimuthally polarized Bessel light beams has been proposed and experimentally realised. This method is based on interaction of radiation with layered periodic medium, including defect impurity - a layer of an uniaxial material. It has been shown that it is possible to control this process by changing the cone angle of the incident Bessel light beam.
