Attenuation of Elastic Waves in the Earth, Physical Acoustics-IIIB
- L. Knopoff
Wave dispersion in heterogeneous solids due to scattering within the microstructure is examined. Underlying physics is explored. A theory based on a quasi-harmonic normal model description of the scattering wave energy is developed and compared with phenomenological nonlinear anelasticity models of wave propagation in heterogeneous media.
