The detailed investigation has been made of the lens effect in plane multilayered metal-dielectric structures (Ag-TiO2). The optical scheme of the lens has been studied with the radiation focusing in free space. The transfer function is calculated, w

A theory of generation of low- and high-index Bessel surface plasmon polaritons and their superposition in a metal film of a finite thickness is developed. Correct analytical expressions are obtained for the field of two families of Bessel surface pl

The transformation of a conical-type light beam by a biaxial crystal during propagation along one of its optical axes is herein investigated. The beam is formed by an axicon from the circularly polarized Gaussian input field. Depending on the positio

In this paper, we investigated the features of plasmon-polaritons excited at the interface of a magnetoelectric hyperbolic metamaterial and a dielectric for the case when the optical axis is arbitrary oriented under the normal to the boundary. Expres

The process of acousto-optic (AO) interaction of Gaussian-like beam and backward Bessel acoustic beam in acoustically transversely isotropic crystals was investigated. AO diffraction on vertically-polarized (SV-) acoustic wave was studied that allowe

A differential polarization interferometer capable of correctly measuring the optical path length in thin metamaterial layers with absorption and reflection losses has been developed. As a result of direct measurement, it is shown that an Ag(28 nm)/S

The acousto-optical Bragg diffraction of Bessel light beams on dispersion Lave waves in a multilayer air-SiO2-Si system was studied as a function of the ultrasonic wave deformation amplitude for layer thicknesses corresponding to the first four Lave

The peculiarities have been investigated of formation of dynamic Airy beams on the basis of acoustic phase cone-lenses at illumination by one or two Gaussian beams with coinciding or orthogonal polarization states. Such light fields are perspective i
