  • About the Edition

    Over the past ten years, electromagnetic metamaterials have become ubiquitous in modern photonics research, following Pendry"s proposal of a perfect flat lens via negative refraction at the turn of the millennium, and the related development of invisibility cloaks. These two paradigms have their counterparts in another emerging subject of wave motion: Acoustic metamaterials, which are locally resonant structures displaying an effective macroscopic behaviour (such as a negative density) beyond Newton"s second law. Applications of acoustic metamaterials range from non-invasive probing and high-resolution tomography in medical imaging, to acoustic camouflaging and seismic protection.

    The twelve chapters constituting this book present an up-to-date survey of many aspects of acoustic metamaterials, including filtering effects, extraordinary transmission, subwavelength imaging via tomography or time-reversal techniques, cloaking via transformation acoustics and elastodynamics and even cloaking via acoustic scattering cancellation and active exterior cloaking. It is hoped that the variety of subjects touched upon in this book, and the ways in which they can be treated theoretically, numerically and experimentally give a grasp of the richness of the emerging topic of acoustic metamaterials and will contribute to initiate even more research activity and applications in the near future.

    The book will be a valuable reference for postgraduate students, lecturers and researchers working on acoustic metamaterials and the wider field of wave phenomena.

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. Introduction This comprehensive book presents all aspects of acoustic metamaterials and phononic crystals.

The emphasis is on acoustic wave propagation phenomena at interfaces such as refraction, especially unusual refractive properties and negative refraction. DESCRIPTION Go beyond conventional materials. This book presents the most recent theoretical developments and numerical/experimental validations of new metamaterials and phononic crystals for the broadband absorption of elastic waves and vibrations in structures.

Abstract Acoustic metamaterial science is an emerging field at the frontier of modern acoustics. It provides a prominent platform for acoustic wave control in subwavelength-sized metadevices or.

The third chapter deals with one of the most promising application of acoustic metamaterials, obtaining a negative refractive index lens which can possibly overcome the diffraction limit. An acoustic system is simulated by the analogous lumped circuit model in which the behavior of the current resembles the motion of the fluid.
