abstract

The spatial structure and polarization of evanescent Bessel light beams excited in an optically less dense medium in conditions of total internal reflection is investigated in detail. TH- and TE-polarized Bessel beams and also their linear superposition are considered. The Pointing vector of evanescent BLBs are calculated. An existence of azimuthal and radial components of the energy flow and also of its z- component, oscillating with the radial coordinate, is established. The structure of the central maximum of a zero- order evanescent BLB is investigated and its diameter is shown being able to be reduced to submicron sizes.
