3. Phononic crystals and acoustic metamaterials: fields of application

3.1 Introduction

Quite obviously, research into phononic crystals and metamaterials explores the potential of these artificial materials as a disruptive technology compared with conventional acoustic wave materials and devices. Acoustic and elastic waves are an integral part of our everyday lives. They are at the heart of a large number of consumer applications, far beyond the obvious problem of audible acoustics. Medical imaging, wireless telecommunications, non-destructive evaluation and vibration mechanics are just some of the key applications for acoustic systems.

The following section seeks to illustrate the potential impact of phononic crystals and acoustic metamaterials through emblematic fields of application. We will limit our considerations to the...
