The process of constructing a stochastic medium model. The size of the model was set to 2 m × 2 m, and the discrete interval was set to 0.01 m. The model parameters, e.g., the background permittivity and standard deviation, are assumed to be 2.89 and 10%, respectively. (A) The Gaussian autocorrelation function. ACF stands for the autocorrelation function. (B) The random phase with a range [0,2π). (C) The random aotocorrelation function. (D) Constructed stochastic medium model.
