Abstract
Holm (see IEEE Trans. Antennas Propag., vol.48, p.1211-19, 2000) has proposed a heuristic UTD diffraction coefficient for nonperfectly conducting wedges as an extension to the heuristic one given by Luebbers (see IEEE Trans. Antennas Propag., vol.32, p.77-6, 2000). The present work improves limitations of Holm´s diffraction coefficient in the illumination region. The improved diffraction coefficient gives results that are very close to the Maliuzhinets (i.e. rigorous) diffraction coefficient. The improvement is valid for parallel and perpendicular field polarisations.
