Scattering attenuation ratios of P and S waves in elastic media
The variation of scattering attenuation ratios of P and S waves (QP-1/QS-1) is investigated in elastic media by using numerical simulations and theoretical expressions based on the first-order Born approximation. Numerical results from stochastic random media (von Karman, exponential, Gaussian) with mild velocity perturbation (10 per cent in this study) are represented well by theoretical attenuation curves with a minimum scattering angle of 60-90°. The level of scattering attenuation ratios is...[Show more]
