Cauchy-like Criterion for Differentiability of Functions of Several Variables
Yurii V. Mukhin, Nataliya D. Kundikova
In this paper, several differentiability criteria for real functions of multiple variables in n-dimensional Euclidean space are considered. Simple and easy-to-use Cauchy-like crite…
New ellipsometric approach for determining small light ellipticities
Nazar Al-wassiti, Evelina Bibikova, Nataliya Kundikova
We propose a precise ellipsometric method for the investigation of coherent light with a small ellipticity. The main feature of this method is the use of compensators with phase de…
Joint effect of polarization and the propagation path of a light beam on its intrinsic structure
Sarkew Abdulkareem, Nataliya Kundikova
The well-known effects of the spin-orbit interaction of light are manifestations of pair mutual influence of the three types of the angular momentum of light, namely, the spin angu…
Influence of light propagation on its polarization in free space
Evelina Bibikova, Nataliya Kundikova
We report the results of experimental observation of the influence of light propagation on its polarization under propagation in free space. These results experimentally prove the…
Transverse shift of a beam with orbital angular momentum under reflection from a dielectric film
N. D. Kundikova, K. A. Zaitsev
We present the results of numerical analysis of Gauss-Bessel beam reflection from a dielectric film under different angles of incidence. A transverse shift of the beam under the or…
Hollow chain-like beams
Dmitriy Cherepko, Nataliya Kundikova, Ivan Popkov
To generate hollow chain-like beams the diffraction of the first order Bessel beam by zone plate with two odd open Fresnel zone has been investigated. It has been shown that the ca…
Properties of an adjustable quarter-wave system under condition of multiple beam interference
Evelina A. Bibikova, Nataliya D. Kundikova
The polarimetric properties of an adjustable two plate quarter-wave system have been investigated. Multiple beam interference within single wave-plates has been taken into account.…
