## Coupling ray series

**Ludek Klimes**
### Summary

We propose a coupling ray series,
which yields the coupling ray theory in a similar way
as the standard ray series
yields the standard ray-theory solution
of the elastodynamic equation.
We insert the coupling ray series into the elastodynamic equation
and obtain the coupling ray theory
as the zero-order high-frequency asymptotic approximation.

### Keywords

Elastic waves, anisotropy, heterogeneous media,
ray series, coupling ray theory, travel time, amplitude, polarization.
