摘要

In this paper, a newly developed discrete multilayer propagation model using scattering theory is studied using rectangular lossy multilayer dielectric plates which model the walls, the streets, and avenues in urban areas. The model is presented to study radio wave propagation in street environments and to compare it with previous theoretical and experimental studies. Good agreements are found. Using the developed model, it is possible to calculate the contributions of direct and scattered wave separately. The simulations reveal that the developed model can be applicable for a broad band of frequencies. This model can be used effectively for prediction of loss characteristics in a situation when two antennas are located below the rooftops in conditions of direct visibility.
