| 摘 要： | The MTF is extended to case of attenuating incident wave by introducing an attenuation coefficient.The reflection coefficients of this modified MTF and MTF are evaluated and compared when an attenuating wave impinges on the 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 is also tested by numerical examples of fluid saturated porous media.

| Abstract: | The MTF is extended to case of attenuating incident wave by introducing an attenuation coefficient. The reflection coefficients of this modified MTF and MTF are evaluated and compared when an attenuating wave impinges on the boundary, and the results demonstrate that MTF can be used to absorb slightly attenuating waves and the modified MTF is more capable of absorbing heavily attenuating waves than MTF. The accuracy of modified MTF is also tested by numerical examples of fluid saturated porous media. |
