Abstract :
A new two-dimensional (2-D) ray-tracing simulator for electromagnetic (EM) propagation prediction in an urban environment is described. The new features are that no practical restrictions are imposed on the profile of the cross section connecting the transmitter to the receiver and that each surface is characterized by its own value for the surface impedance; also, second-order diffraction coefficients for impedance wedges are used to allow for arbitrary values of the heights of both antennas. Comparisons with other methods and numerical results are presented
