In this study, heuristic uniform theory of diffraction coefficients are suited to account for scattering by lossy conducting wedges.The novel heuristic solution is determined from other previously developed heuristic coefficients, combining their characteristics to improve the estimation of radiowave propagation in urban scenarios. Slope diffraction is also considered to account for double‐diffracted fields in consecutive wedges. Maliuzhinets' coefficients provide base solutions to validate the novel formulation. The novel solution is then applied to the wave propagation in a typical urban scenario, and results are compared against measurements provided in the literature. © 2010 Wiley Periodicals, Inc.
