【Abstract】 Based on GTD, this paper presents accurate tracing equations for the diffraction ray on the cone and cylinder which are suitable for both the far field and the near field and more accurate than those in the literature published in recent years. Numerical results agree with those in the reference in the case of the far field. By this method satisfactory results are obtained in engineering computation.
