Progress toward a benchmark solution for 3-D, perfectly conducting scatterers with edges and corners

The authors present the predicted and measured E-plane, H-plane, and 45 degrees -plane scattered fields from the perfectly conducting cube for broadside plane-wave incidence. Although the scattering patterns are obtained for a plane-wave incident broadside upon the front face of the cube, the magnetic-field integral equation solutions can easily accommodate plane-wave illumination from an arbitrary direction, or illumination by an incident field other than a plane wave. However, the uniform high-frequency solution is valid only for broadside plane-wave incidence.<>
