Statistical properties of a stochastic electromagnetic pulse scattering by a quasi-homogeneous random medium

Intensity Evolution of Cosine-Gaussian-Correlated Schell-Model Pulse Scattered by a Medium

“…The basic concepts and representations of partially coherent pulses were established [8,9]. In the discussion of pulsed-beam scattering [10][11][12][13][14][15][16], the initial pulse was fully or partially coherent, and the complex degree of coherence of the majority of these partially coherent pulses is a conventional Gaussian Schell-mode function [17]. In recent years, a large number of partially coherent sources with other types of Schell-mode coherence were proposed, e.g., nonuniform-correlation [18], multi-Gaussian Schell-model [19,20], Laguerre-Gaussian and Hermite-Gaussian Schell-model [21], and sinc-correlation sources [22].…”

Far-zone behaviors of scattering-induced statistical properties of partially polarized spatially and spectrally partially coherent electromagnetic pulsed beam*

“…[6] In the past several decades, the findings about scattering media have focused on various types of scattering media, such as a deterministic medium, [1][2][3]7,8] a collection of particles, [4] and a random medium including a quasi-homogeneous media, [9] a Gaussian Schell-model random medium, [10,11] a semisoft boundary medium, [12] a non-Gaussian-correlated medium, [13] and a quasi-homogeneous anisotropic medium. [14] Additionally, the incident sources have also been extended from monochromatic or polychromatic, scalar or vector plane waves to more common beams, such as partially coherent beams, [15,16] stochastic electromagnetic beams, [7,17,18] plane-wave pulses, [3,19] and vortex beams. [8] For these incident sources, considerable work has been done in illustrating the scattering processes based on the theory of the first-order Born approximation.…”

“…[8] For these incident sources, considerable work has been done in illustrating the scattering processes based on the theory of the first-order Born approximation. [7][8][9][10][11][12][13][14][15][16][17][18][19] However, most of the existing studies were restricted to the situation in which the incident source was statistically stationary, at least in the wide sense. [4][5][6][7][8][9][10][11][12][13][14][15][16][17] To date, only a few studies have focused on a non-stationary source.…”

“…[4][5][6][7][8][9][10][11][12][13][14][15][16][17] To date, only a few studies have focused on a non-stationary source. [2,3,18,19] A typical non-stationary stochastic source called spatially and spectrally partially coherent pulses was introduced by Lajunen et al [20] By extending the notion of the CSD matrix from stochastic electromagnetic stationary beams to stochastic electromagnetic pulsed beams, we explored the propagation properties of a partially polarized spatially and spectrally partially coherent electromagnetic Gaussian Schell-model pulsed (EGSMP) beam in a turbulent atmosphere. [21][22][23] To the best of our knowledge, an investigation of the statistics of a partially polarized spatially and spectrally partially coherent electromagnetic pulse irradiating on a deterministic scattering medium has not been presented thus far.…”
