Studies of Rayleigh scattering of longitudinal waves in saturated porous materials

摘要

The paper presents experimental results and a model for propagation of ultrasonic waves in fluid saturated porous material. The model aimes at development of a two-phase description of the media assuming the presence of pore and solid scattering represented by complex and frequency dependent elastic moduli. A simple procedure allowing for determination of scattering parameters is proposed and comparison of model prediction and experimental data for attenuation of longitudinal waves is performed.
