Elastic waves possess some remarkable properties and it is these that explain their important role in the processing of electronic signals and the sensing of physical quantities. For example, they can be generated by localized or distributed sources, can propagate in the core or on the surface of optically transparent or opaque solids, have velocities one hundred thousand times less than those of electromagnetic waves, and they can modify the characteristics of a light beam. The purpose of this second volume is to illustrate the functions fulfilled by the free and guided waves described in Vol. I. It deals with the generation of bulk waves using piezoelectric resonators, generation of surface waves by interdigital transducers, interaction between elastic waves and light waves, acousto-electronic filters, acousto-optic components, sensors and instruments.

Elastic waves are used in fields as diverse as the non-destructive evaluation of materials, medicine, seismology and telecommunications. Elastic Waves in Solids 1 presents the different modes of propagation of elastic waves in increasingly complex media and structures. It first studies the propagation in an unlimited solid where only the material properties are taken into account. It then analyzes reflection and transmission phenomena at an interface with a fluid or a second solid.It explains the search for propagation modes on a free surface or at the interface between two media. Finally, it proposes a study of the dispersive propagation of elastic waves guided by a plate or a cylinder. This book is intended for students completing a master's degree in acoustics, mechanics, geophysics or engineering, as well as teachers and researchers in these disciplines.

Elastic waves possess some remarkable properties and have become ever more important to applications in fields such as telecommunications (signal processing), medicine (echography), and metallurgy (non-destructive testing).
