Electromagnetic non-uniformly correlated beams in turbulent atmosphere

Abstract

Electromagnetic random beams with non-uniform source correlations have been recently shown to develop, on propagation in free space, the regions in transverse cross-sections where the degree and the state of polarization can significantly differ from those beyond that region. The size of the region and the values of polarimetric properties in it can be fully controlled from the source plane. In this paper the influence of a random isotropic medium on such beams is shown to suppress the effect in several ways, in particular by shifting the location of the region back to the axis.

Effects of astigmatism on spectra and polarization of aberrant electromagnetic nonuniformly correlated beams in turbulent ocean

“…(11) can be found, on combination of Eqs. (13) and (14) with Eq. (3), and applying numerical integration.…”

“…However, the only model beam that not being of uniform correlation (e.g., Schell-model correlation) is the spatially varying correlated sources, proposed in [10,11]. In recent years, more and more attention has been paid to these beams with special correlation distribution [12][13][14][15][16][17], due to their interesting features, such as locally sharpened and laterally shifted intensity maxima [4]. The behavior of scalar beams of nonuniform correlation, in isotropic random media, was explored in [12], which introduced a class of electromagnetic beams with nonuniform correlation distribution [5].…”

“…The behavior of scalar beams of nonuniform correlation, in isotropic random media, was explored in [12], which introduced a class of electromagnetic beams with nonuniform correlation distribution [5]. The propagation properties of electromagnetic nonuniformly correlated (EMUNC) beams, in a turbulent atmosphere, was studied in [13]. The scintillation properties of NUC beams, in atmospheric turbulence, were investigated in [14].…”

Effect of the atmospheric turbulence on a special correlated radially polarized beam on propagation

“…Thus, modulating the correlation functions of laser beams provides an optional way to reduce the negative effects in the atmosphere. Meanwhile, the other propagation properties such as average intensity distribution and degree of coherence, of such kinds of partially coherent beams including cosine-Gaussian correlated Schell-model (CGCSM) beam [38][39][40], NUC beam [41,42], LGCSM beam [43,44] have been extensively studied. However, the statistical properties of the SCRP beam propagation through atmosphere have not been reported yet.…”

Scintillation of nonuniformly correlated beams in atmospheric turbulence

“…Unlike GSM beams, these beams have a spatially variant correlation function [5], and also are referred to as nonuniformly correlated (NUC) beams [6]. Their propagation characteristics in the atmosphere have been investigated recently [7,8]. One intriguing feature of such beams is that focused modes are contained in the representation of a NUC beam and consequently the beam obtains a sharp on-axis maximum some distance beyond the source plane [5].…”
