Viscoelastic Waves and Rays in Layered Media

This edition extends the theory for viscoelastic wave propagation to include head waves and general ray theory. The additions, not published elsewhere, significantly increase interest in the book for advanced university courses, research, and applications in seismology, exploration geophysics, engineering, solid mechanics, acoustics, and physics.

This second edition extends the rigorous, self-contained exposition of the theory for viscoelastic wave propagation in layered media to include head waves and general ray theory. The theory, not published elsewhere, provides solutions for fundamental wave-propagation and ray-theory problems valid for any media with a linear response, elastic or anelastic. It explains measurable variations in wave speed, particle motion, and attenuation of body waves, surface waves, and head waves induced at anelastic material boundaries that do not occur for elastic waves. This book may be used as a textbook for advanced university courses and as a research reference in seismology, exploration geophysics, engineering, solid mechanics, and acoustics. It provides computation steps for ray-tracing computer algorithms to develop a variety of tomography inferred anelastic models, such as those for the Earth''s deep interior and petroleum reserves. Numerical results and problem sets emphasize important aspects of the theory for each chapter.
