Propagation of the fourth-order coherence function in an anisotropic random medium

Research output: Contribution to journalArticlepeer-review


The propagation of the fourth-order coherence function through an anisotropic random medium is investigated for low frequency radiation using the parabolic approximation and perturbation techniques. Theoretical expressions are derived for the intensity fluctuations and correlations of an initial plane wave signal that has propagated a horizontal distance z into the medium. The expressions are valid for anisotropic media in which klH≫1 and klV2/lH≪1, where k is the radiation wavenumber, lH and lV are, respectively, characteristic correlation lengths parallel and perpendicular to the propagation direction z. The results are compared to those obtained for an isotropic random medium.
