Abstract :
The electromagnetic scattering of a plane wave by a metallic sphere concentric with a circular disk is considered, in the frequency domain. At low and intermediate frequencies, either separation of variables and mode-matching with matrix truncation or a direct numerical approach such as the method of moments may be used, whereas at high frequencies a combination of geometrical theory of diffraction (GTD) and physical optics (PO) is employed.
