摘　　要：A novel finite-difference (FD) approximation in frequency-domain for the Mur boundary condition is presented in this paper. Combined with the FD equations derived for inhomogeneous anisotropic media, this boundary condition is convenient and effective to be applied to the EM scattering by electrically large objects of complex media. Both the memory requirement and the computing time are dramatically saved, compared with the MM, with the compressed storage technique. For the cases of different media, RCS of circular and rectangular cylinders are computed. Good agreement is obtained between the results by this method and those available.A novel finite-difference (FD) approximation in frequency-domain for the Mur boundary condition is presented in this paper.
