Summary 
The objective of this book is to treat the behavior of ultrasonic waves as they interact with layered, anisotropic materials incorporating those structural aspects unique to composite laminates addressing both experimental and modeling methodologies. Anisotropic material interfaces, guided waves, waves in layered media and laminated plates are treated. The influence of finiteaperture transducers on electronic signals and the field of aircoupled ultrasonics end the work
