Frequency-domain ray series for viscoelastic waves with a non-symmetric stiffness matrix

Ludek Klimes

Summary

In an elastic medium, it was proved that the stiffness tensor is symmetric with respect to the exchange of the first pair of indices and the second pair of indices, but the proof does not apply to a viscoelastic medium. In this paper, we thus propose the frequency-domain ray series for viscoelastic waves with a non-symmetric stiffness tensor.

Keywords

Viscoelastic media, stiffness tensor, wave propagation, ray theory, ray series, travel time, amplitude.
