Green's tensor and radiation patterns of point sources in general anisotropic inhomogeneous elastic media

The elastodynamic 'ray-theoretical' Green's tensor for general anisotropic and inhomogeneous media (GANIMED) is derived in the far-field high-frequency approximation. This allows the quantification of the amplitude and phase characteristics of arbitrary point sources. The displacement field is controlled by the phase velocity and the Gaussian curvature of the wave surface.
