摘要：
A comparative study of some theoretical and numerical models is presented in the solution of two-dimensional urban radiowave propagation problems. The path loss is computed by GO+UTD (geometric optics + uniform theory of diffraction), two-way SSPE (split step parabolic equation) and the diffracting screens models, and the results are compared through numerical simulations. The diffracted fields that are obtained by the GO+UTD model are demonstrated. Computational aspects of the models are briefly discussed.
