Abstract :
An asymptotic ray solution is obtained for the collective surface field produced by a large aperture that is conformal to a smooth convex metallic surface. It is expressed in closed form as a few surface rays emanating from specific points on the aperture boundary to propagate along the geodesic surface ray paths to the observation point on the surface.
