## Analytical one-way plane-wave solution
in the 1-D anisotropic "twisted crystal" model

**Ludek Klimes**
### Summary

The exact analytical expressions for the 2*2 one-way
propagator matrices of plane S waves, propagating along the axis
of spirality in the simple 1-D anisotropic "twisted crystal" model,
are presented.
The analytical equations may be useful to test and debug
approximate and numerical methods, e.g.,
the coupling ray theory,
the high-order anisotropic ray theory or the finite differences.
The exact solution is compared with the analytical equations for the
coupling ray theory and zero-order anisotropic and isotropic
ray theories.

### Keywords

Anisotropy, S-wave coupling, polarization, elastic waves, exact solution.
