摘要：

Based on the matrix method, a theory of propagation of vector Bessel light beams (BLBs) in a one-dimensional photonic crystal (1DPC) is developed. The transmission through a 1DPC (with and without a defect impurity-a layer of a uniaxial crystal) has been calculated and analyzed. Based on this, a method of highly effective generation of Bessel vortices has been proposed. The conditions for the highly effective transformation of an incident (m - 1)-order Bessel beam into a transmitted through 1DPC Bessel beam of (m + 1) order are derived. The influence of parameters of the structure (refractive indices and thicknesses of the 1DPC component) and cone angle of the incident BLB on the process of this transformation is analyzed.
