Abstract

This paper discusses the decoupled attenuation property of the viscoelastic wave equation. Because of the decoupling, wave propagation can be simulated in three scenarios: only amplitude loss effect, only phase dispersion effect, or both effects, which brings practical convenience, especially seismic inverse problems. Wavefield reconstruction can be accomplished simply by reversing the signs of both the P- and S-wave loss operators. Therefore, attenuation effects are thus compensated for during back-propagation. Several numerical examples are used to demonstrate the advantages of the decoupled attenuation property in both viscoelastic wave propagation and wave-field reconstruction.
