Stochastic Electromagnetic Scattering From Stratified Media of Inhomogeneous Layers With Random Constitutive Parameters

In this article, we develop an accurate and fast numerical method to analyze stochastics scattering from stratified media consisting of inhomogeneous layers with random constitutive parameters. The permittivity and/or permeability of each layer may vary continuously. Full-domain cubic B-spline basis functions are employed in the stochastic method of moment (SMoM), for calculating the scattered fields by converting the governing Helmholtz’s differential equation to a matrix form. It is shown that the complexity of the proposed full-wave approach is not affected significantly by the number of existing random parameters. The proposed method is vindicated by comparing its results with the Monte Carlo (MC) method.
