Coherence properties of the scattered electromagnetic field generated by anisotropic quasi-homogeneous media

Polarization Properties of Quasi-Homogeneous Beams Propagating in Oceanic Turbulence

“…Without loss of generality, the spectral density and correlation coefficients can be described by the Gaussian-Schell model: (4) A is spectral amplitude which we set A=1 in this article, and B ij is called the coefficient of correlation between the incident field components, for quasi-homogenous beams, it can be set as: B xx =B yy =1, B xy =B * yx , where the asterisk means complex conjugate. σ represents the width of the source, δ ij represents the coherent width of the source.…”

“…The coherence of properties of the field generated by a beam radiated from a quasi-homogenous electromagnetic source scattering on QH media has been studied by Xin [3]. Chen and Li have been researched the coherence properties and polarization modulation of QH beams scattered from anisotropic media [4][5]. The propagation properties of laser beams in random media like turbulence or human tissue are important for applications such as optical imaging, remote sensing and communication systems so more and more researchers are attracted [6][7][8][9][10][11].…”

Polarization-induced coherence changes and conditions for the invariance of the spectral degree of coherence produced by an electromagnetic wave scattering on a collection of particles

“…Within the accuracy of the first-order Born approximation [8,16], the cross-spectral density matrix of the scattered field is derived…”

“…Meanwhile, the inverse problem, i.e., the determination of the density correlation functions for a collection of particles was studied [5], and the method to determine the pair-structure factor of a collection of particles was discussed [6]. Besides, the cross-spectral density function of the scattered field produced by a coherent plane light wave incident on a collection of different types of anisotropic particles was derived in [7,8]. In the past two decades, numerous papers were published on the analysis of scattering by deterministic or random distributions of identical or disparate particles.…”

Scattering of electromagnetic light waves from a deterministic anisotropic medium

“…In these literature, it was stipulated that the spatial anisotropy of a medium can be described by the effective radii of the dielectric susceptibility. As an extension work, a generalization model of an anisotropic quasihomogeneous (QH) medium was introduced [18]. It was shown that the anisotropic medium, which occupies different effective radii of the dielectric susceptibility should additionally have different correlations for each element of the scattering potential.…”
