WebInitially, Stroh formalism was applied to analysis of Rayleigh waves propagating on a free boundary of an anisotropic half-space [49–55]. The case of the nonsemisimple degeneracy of the fundamental matrix was considered in [ 53 ] (that case is associated with appearing multiple roots and the coincident kernel eigenvectors in the Christoffel equation).
