Polarization is measured very often to study the interaction of light and matter, so the
description of the polarization of light beams is of both practical and fundamental interest …

The Letter develops a modified geometrical optics (GO) of smoothly inhomogeneous
isotropic medium, which takes into account two topological phenomena: Berry phase and …

We present a modification of the geometrical optics method, which allows one to properly
separate the complex amplitude and the phase of the wave solution. Appling this …

The propagation of electromagnetic waves in isotropic dielectric media with local dispersion
is studied under the assumption of small but nonvanishing λ/ℓ, where λ is the wavelength …

The well-known effects of the spin-orbit interactions of light are manifestations of the pair's
mutual influence of the three types of angular momentum (AM) of light, namely, the spin AM …

Topological spin transport of electromagnetic waves (photons) in stationary smoothly
inhomogeneous isotropic medium is studied. By diagonalizing the photon kinetic energy in …

We study theoretically the process of conversion of the topological charge of optical vortices
upon their propagation in anisotropic and elliptical weakly guiding optical fibres. We …

Propagation of an electromagnetic wave in a layered locally isotropic medium is considered.
An effective birefringence n∥-n⊥∼(λ/a) 2 for the∥ and⊥ eigenpolarizations appears, and …

Spin–orbit coupling and nonparaxiality effects during the propagation of vortex vector light
beams in a cylindrical graded-index waveguide are investigated by solving the full three …

Spin-orbit interactions (SOI) arising due to the propagation of a paraxial light beam, with spin-
angular momentum and intrinsic-and extrinsic-orbital angular momentum degrees of …
