Opis

A treatment of various generalizations of the classical O'Doherty-Anstey formula in order to describe stratigraphic filtering effects. These are the effects that can be observed when elastic and electromagnetic waves propagate through multilayered structures. The book's aim was to treat this topic in a comprehensive manner and present compact results in a didactically simple way, emphasizing the physics of the wave propagation phenomena. It does not claim mathematical rigidity in all its derivations, but provides quite simple descriptions of scattering, transmission and reflection of wavefields in acoustic, elastic and poroelastic media which can be useful for various seismological and non-seismological applications.
