Abstract

Sound wave propagation in continuous inhomogeneous media plays an important role in various physical phenomena (e.g. earthquakes [1]) as well as in technological applications (such as oil exploration [2], non-destructive evaluation [3], ultrasound in medicine [4], underwater acoustics [5], etc). The relatively large number of material parameters (mass density, ρ, and velocities of the longitudinal, c1, and transverse, ct, components of the sound wave) and the full vector character of the wave give a rich physics.
