Radio Wave Propagation Prediction for Forests in Rainy Environment

An efficient parabolic equation solver is proposed to predict the radio wave propagation in forest during the rainy seasons. The method starts with considering the forest model as a mixture of plants and rain particles. Then the equivalent dielectric constant model can be used to simplify the calculation process. At last, the Split-step Fourier transform (SSFT) is used to calculate the loss of radio wave propagation in the forest. Numerical results show that this model can calculate the propagation loss of forests in rainy environment.
