Features of evanescent Bessel light beams formed in structures containing a dielectric layer

摘要

Based on the matrix method, a theory of generation of evanescent Bessel light beams (BLBs) in a structure containing a dielectric layer is developed. An exact solution is obtained for the problem of the tunneling of vector BLBs (TE and TM modes and their linear superposition) through the layer surrounded by various dielectric media in conditions of the total internal reflection at its boundaries. The behavior of energy fluxes both inside the layer and in ambient media is investigated.
