| Abstract: | The parabolic equation(PE) method is applied to analyze scattering characteristics of objects.As obvious errors may occur in the calculations of scatterers with edges by the traditional PE method,edge diffraction is considered to improve the PE method.Numerical results suggest that the new method can improve the accuracy of computation for scatterers with edges. |
