3D Diffraction of a Complex Source Beam by a PEC Wedge

The scattering and diffraction of a 3D Complex-Source Beam (CSB) by a wedge made from a perfect electric conductor (PEC) is analyzed in this paper. The analytic solution is based on the corresponding scalar (acoustic) fields where both soft and hard boundary conditions have to be considered at the wedge faces. In particular, a new spherical-multipole solution is presented for an incident uniform CSB which consists of both diverging and converging parts. First numerical results include the scattering and diffraction of a scalar 3D uniform CSB by both acoustically soft and hard wedges.
