In the last few decades, metamaterials have revolutionized the ways in which waves are controlled, and applied in physics and practical situations. The extraordinary properties of metamaterials, such as their locally resonant structure with deep subwavelength band gaps and their ranges of frequency where propagation is impossible, have opened the way to a host of applications that were previously unavailable. Acoustic metamaterials have been able to replace traditional treatments in several sectors, due to their better performance in targeted and tunable frequency ranges with strongly reduced dimensions.
This is a training book composed of nine chapters written by experts in the field, giving a broad overview of acoustic metamaterials and their uses. The book is divided into three parts, covering the state-of-the-art, the fundamentals and the real-life applications of acoustic metamaterials.
Part 1. Overview of the Current Research in Acoustic
1. Visco-thermal Effects in Acoustic Metamaterials Based on Local Resonances, José Sanchez-Dehesa and Vincente Cutanda Henriquez.
2. Locally Resonant Metamaterials for Plate Waves: the Respective Role of Compressional Versus Flexural Resonances of a Dense Forest of Vertical Rods, Martin Lott and Philippe Roux.
3. Slow Sound and Critical Coupling to Design Deep Sub wave length Acoustic Metamaterials for Perfect Absorption and Efficient Diffusion, Vincente Romero-Garcìa, Noé Jiménez and Jean-Philippe Groby.
Part 2. Principles and Fundamentals of Acoustic Metamaterials
4. Homogenization of Thin 3D Periodic Structures in the Time Domain – Effective Boundary and Jump Conditions, Agnès Maurel, Kim Pham and Jean-Jacques Marigo.
5.The Plane Wave Expansion Method, Jérôme Vasseur.
6. Introduction to Multiple Scattering Theory, Logan Schwan and Jean-Philippe Groby.
Part 3. Applications of Acoustic Metamaterials
7. Acoustic Metamaterials for Industrial Applications, Clément Lagarrigue and Damien Lecoq.
8. Elastic Metamaterials for Radio Frequency Applications, Sarah Benchabane and Alexandre Reinhardt.
9. Acoustic Metamaterials and Underwater Acoustics Applications, Christian Audoly.
