This paper is concerned with a theoretical discussion on the simplification of analyses of the electromagnetic diffraction by an edge or a wedge and their application to multi-wedges diffraction. The final goal of this paper is to effectively estimate the propagation characteristics in urban areas especially focusing on polarization conversion. First, starting from, the rigorous solution to the plane wave diffraction by a conducting half plane, we derive an approximate solution for the wedge diffraction of an incident spherical wave by using the source and image coefficients. Next, we propose on approximation for the multi-edges diffraction; we include the principal part of the diffraction but ignore the higher order of multiple diffractions assuming that the latter effect on propagation is small compared with the former. Numerical results are shown for statistics of diffraction phenomena.
