Besides the basic principles of the ray theory, several recently introduced and applied concepts are described. Attention is paid to the coupling ray theory for S waves propagating in anisotropic media. Some space is devoted to the combination of perturbation methods with the ray method. One very useful concept developed on this basis is the weak-anisotropy approximation, which found recently many applications in exploration seismics, and which can also be used in the S-wave coupling problem. Another application of the perturbation method is the weak-attenuation approximation. The entry contains references to many other innovative approaches.
