Wave Fields in Real Media: Wave Propagation in Anisotropic, Anelastic, Porous and Electromagnetic Media

Wave Fields in Real Media: Wave Propagation in Anisotropic, Anelastic, Porous and Electromagnetic Media discusses the differences between an ideal and a real description of wave propagation, using Biot theory to describe wave propagation in porous media. It also covers new topics such as the S-wave amplification function, Fermat principle, seismic Q, seismic attenuation in partially molten rocks, and direct numerical methods for solving the equation of motion.

Wave Fields in Real Media: Wave Propagation in Anisotropic, Anelastic, Porous and Electromagnetic Media delves into the disparities between an ideal and a real portrayal of wave propagation, commencing with the introduction of pertinent constitutive relations. The differential formulation can be expressed in terms of memory variables, and Biot theory is employed to describe wave propagation in porous media. For each constitutive relation, a plane-wave analysis is conducted to elucidate the physics of wave propagation. New topics covered include the S-wave amplification function, Fermat principle, and its relationship to Snell law, bounds and averages of seismic Q, seismic attenuation in partially molten rocks, and more. This comprehensive book serves as a review of the primary direct numerical methods for solving the equation of motion in both the time and space domains. While the primary focus lies in geophysical applications for seismic exploration, researchers in the domains of earthquake seismology, rock acoustics, and material science, including numerous branches of acoustics of fluids and solids, will also find this text invaluable.
