Abstract :
The material corner diffraction (CD) solution summarized here has been found to yield very accurate results for the far zone scattering from electrically large material structures made up from flat plates. The solution is presented for an impenetrable, convex material vertex in terms of the perfect electric conductor (PEC) CD coefficients and the reflected components of the geometrical optics (GO) field. The extension to the more general penetrable case is described and numerical results are presented for a penetrable two-plate shell. The solution may be extended to curved surface geometries with tips and corners using the same technique of modifying the PEC diffraction solution via comparison of the PEC and material physical optics (PO) solution.
