The scattering process of cylindrical waves by a convex hyperbolic reflector

In this thesis, the scattered fields by a perfectly conducting convex hyperbolic reflector were investigated by using the methods of modified theory of physical optics and physical optics. Furthermore, the geometrical optics and edge diffracted fields were evaluated by the stationary phase method and the edge point technique, respectively. The uniform diffracted field expressions were obtained by the method of the uniform theory of diffraction. Moreover, the results of modified theory of physical optics and physical optics were plotted and compared numerically. The results of geometrical optics and uniform diffracted fields were also plotted and analyzed numerically.
