  • Abstract
    The application of the generalized multipole technique to solve the problem of sharp edges is described. The treatment includes: a special discretization of the boundary near the singularity; one or several extra multipoles for this special region; the division of the domain into several fictitious subdomains for lossy materials; and an appropriate weighting for ideal conductors. The near-field problem for a cylinder with a conical top and a comparison of the radar cross sections of cylinders with different tops are considered as examples.<>
