A New Heuristic UTD Diffraction Coefficient for Nonperfectly Conducting Wedges

Peter D. Holm

Page 1211.

Abstract:

A new heuristic UTD diffraction coefficient for nonperfectly conducting wedges is proposed. The coefficient is an extension of the heuristic one given by Luebbers and as simple as that to compute. In the case of forward-scattering and neglecting the surface wave effects, the new coefficient gives a result close to Maliuzhinets's solution, also deep in the shadow region where the previous one fails. Moreover, it makes the special care used by Luebbers to deal with grazing incidence unnecessary.
