Abstract

Modelling of high frequency waves propagation in urban areas is of great interest. This paper proposes a solution for a basic problem encountered in this general study: field diffraction by a dielectric wedge (building wedge), and specially a model for a three dimensional analysis. Mathematical aspects based on the uniform theory of diffraction and previous works are presented in the first part. Then, experiments at 1.5 GHz are described and a good agreement between numerical model and measurements is verified. The signal losses due to the masking effect are evaluated and the depolarization of the diffracted wave is also shown
