  • Abstract
    The uniform geometrical theory of diffraction (UTD) is applied to consider three-dimensional terrain effects on high frequency wave propagation. Planar convex polygons are used to approximate a given terrain and the electrical characteristics of each polygon are given through the relative dielectric constant and the conductivity. The roughness can be considered approximately as well. A heuristic uniform diffraction coefficient is derived for an imperfectly conduting wedge.
