摘要：

AbstractThe MTF is extended to case of attenuating incident wave by introducing an attenuation coefficient.The reflectioncoefficients of this modified MTF and MTF re evaluated and compared when an attenuating wave impinges onthe boundary,and the results demonstrate that MTF can be used to absorb slightly attenuating waves and the modi-fied MTF is more capable of absorbing heavily attenuating waves than MTF.The accuracy of modified MTF isalso tested by numerical exaamples of fluid saturated porous media.
