Abstract
Specific features of tunneling of optical beams in the band gap of a plane-layered structure with finite thickness are considered. Typical profiles of transmitted beams and 2D spatial distribution of field intensity in the periodic structure are calculated at several ratios of the spectral width of the obliquely incident beam to the angular width of the band gap. Integral lateral displacements of the transmitted beams are calculated, and the saturation limits of such displacements are determined upon an increase in the layer thickness. Several features of the tunneling of convergent and divergent beams are outlined.
