Notes on the CREWES AniZoeppritz Explorer

The AniZoeppritz Explorer is similar in operation to the CREWES Zoeppritz Explorer and to the CREWES Reflectivity Explorer. Those web pages should be referred for notes on general use. The present utility differs in that it explores the behavior of the P-wave reflection coefficient in the presence of anisotropy. The present version (June 2002) can calculate exact coefficients for VTI (vertical transverse isotropy) media, and linearized coefficients for both VTI and HTI (horizontal transverse isotropy) media. For comparison it can also calculate exact (Zoeppritz) and linearized (Aki-Richards) coefficients for corresponding isotropic media.

For a reference on exact VTI coefficients see Daley & Hron, 1977, "Reflection and transmission coefficients for transversely isotropic solids", Bull. Seis. Soc. Am., 67, 661-675. For a reference on linearized coefficients see Ruger, 1997, "P-wave reflection coefficients for transversely isotropic models with vertical and horizontal axis of symmetry", Geophysics, 62, 713-722.
