Extensional method was presented for the origin of Gedney perfectly matched layer(PML) absorbing boundary condition could not be used in truncation of lossy media and was not effective in absorbing evanescent waves. The main idea of extensional PML was to overcome the limitation of Gedney PML by deriving complex permittivity and complex permeability from lossy media to PML. Evanescent coefficient was put forward also to accelerate evanescent wave fading down. The computational model was designed to study the reflection of PML to lossy media. The numerical results prove that the extensional method is very efficient in terminating computational domain composed of lossy media. The extensional PML was used in FDTD method to simulate the EMP effect of a ground laying shielded cable. Compared wi
