| Extension of material independent Perfectly Matched layer to dispersive media is made in this paper and perfectly matched condition for dispersive media is derived. Numerical experiment is done in lossy media and good result is achieved. Comparing with Q.H.Liu"s method, the method can be used to more complicate material and comparing with S.D.Gedney"s anisotropic material absorber, calculation in the corner region is more simple therefore, it is more suitable for FDTD, especially in three-dimension case. |
