heal.abstract In this paper an accurate method for the calculation of the diffracted electromagnetic field from rectangular wedges in the near and Fresnel-zone field areas is introduced. The proposed technique, which is based on the analytical method of physical theory of diffraction (PTD), is applicable for the radio-propagation prediction in urban outdoor microcellular environments where the near-field diffraction from building wedges is one of the dominant propagation mechanisms, mainly in the non-line-of-site (NLOS) regions. Comparisons between the results obtained from this method with the corresponding results based on different high- frequency diffraction techniques in the far-field area, as well as the efficient convergence of the simulation results in the near\Fresnel-zone field areas, validate the excellent accuracy of the proposed methodology, as well as the significant correction of the received signal near the building wedges. en
