Ellipsoidal surface characterization for validating the UTD formulation

The UTD mutual coupling results are presented for an ellipsoid of revolution, for slots located arbitrarily on the surface. Rigorous 3-dimensional ray tracing has been performed by the geodesic constant method. The ellipsoid of revolution, with unequal double curvature surfaces without any edges, provides an ideal surface for verifying the heuristics involved in the UTD (surface-diffracted) formulation.
