This book highlights the acoustical metamaterials' capability to manipulate the direction of sound propagation in solids which in turn control the scattering, diffraction and refraction, the three basic mechanisms of sound propagation in solids.

This book highlights the applications of signal and image processing to acoustical imaging. The book also details the design of digital filters and array signal processing, before examining applications to image processing in the final section: image enhancement and optimization, image restoration, and image compression.
