Summary:

The diffraction of sound by hard geometrical shapes has been studied by the Method of Moments (MOM), a boundary element technique for solving the scalar Helmholtz integral equation. The scattered fields of several rectilinear shaped objects are analyzed. The problem of scattering by an axially-symmetric obstacle has been simplified by using the symmetry to reduce the computational load. The validity of the resulting procedure has been verified by comparing the MoM results for a flat circular disk illuminated by either a plane or spherical wave with the results obtained by the classical method of separation of variables and expansion in oblate spheroidal wave functions.
