Attenuation and dispersion of elastic waves in porous rocks : mechanisms and models /

Wave propagation in all fluid and solid matter is always accompanied by attenuation and dispersion in a broad range of frequencies and scales from free oscillations of the entire Earth to ultrasound in small rock samples. Attenuation is the exponential decay of wave amplitude with propagation distan...
