Abstract : This report deals with the geometrical theory of diffraction (GTD) solution to the problem of plane wave high frequency (h.f.) scattering by a smooth, perfectly-conducting cylindrical surface. According to the GTD, the surface diffracted rays accurately describe the field behavior deep in the shadow region behind the obstacle; whereas, the incident and reflected rays adequately describe the field in the lit region sufficiently far from the optical shadow boundary.
