The application of the method of moments usually requires a minimum degree of differentiability for basis and testing functions. Through the solution of the electric field integral equation (EFIE) for scattering by a perfect conducting cylinder illuminated by a TE wave, however, it is shown that such a restriction can be loosed. Theoretically, pulse basis functions and point matching are usually considered...
The recently developed on-surface discretized boundary equation method for scattering by conducting cylinders was based on scattered field expressions in terms of true electric surface currents. In this paper, an alternative form of the method is derived by making use of virtual magnetic surface currents. Numerical results are presented to demonstrate its validity and applicability. A comparison between...
A unified approach, named discretized boundary equation (DBE) method, is introduced for two-dimensional (2-D) scattering problems. It is based on the discretization of field expressions for one or two components of the scattered field. The DBEs can be used either on the object surface to obtain the solution directly or on the truncation boundary of a finite difference (FD) or finite element (FE) mesh...
