| Abstract: | The multiform approximation of pseudo-differential operator of parabolic equation(PE) method and the characteristics of PE method after the approximation are analyzed.Multiform PE methods are applied to analyzing the scattering characteristics of electrically large objects.The numerical results conducted on the scattering from perfectly conducting cylinder demonstrate that each of multiform PE methods after the approximation has special characteristics and application scope. |
