| Abstract: | Based on the physical optics(PO) theory,the geometrical theory of diffraction,the principles of equivalence and impedance boundary condition(IBC),coupling matrix was derived from the eigenequations of plane waves in anisotropic medium.Then the transmission matrix and the reflection matrix were obtained.Scattering fields of complex target coated with anisotropic radar absorption material(ARAM) were calculated using the method of graphical electromagnetic computing.It is shown that the method is characterized by high computing efficiency and less memory,and is useful in computing RCS of an electrically large target with a surface coated medium. |
