Special issue of Comptes Rendus Physique on phononic crystals

The May 2016 issue of Comptes Rendus Physique, an international peer-reviewed journal of the French Academy of Sciences published by Elsevier, is devoted to phononic crystals. The special issue was coordinated by Vincent Laude, a research director at CNRS and a member of the Micro Nano Sciences & Systems department of FEMTO-ST.

Phononic crystals are artificial periodic structures that can alter efficiently the flow of sound in air, of acoustic waves in fluids, or of elastic waves in solids. They were introduced about twenty years ago and have gained increasing interest since then, both because of their amazing physical properties and because of their potential applications. The topic of phononic crystals stands at the cross-road of several fields of physics - condensed matter physics, wave propagation in inhomogeneous and periodic media - and engineering - acoustics, ultrasonics, mechanical engineering, and electrical engineering. Phononic crystals cover a wide range of scales, from meter-size periodic structures for sound in air to nanometer-size structures for information processing or thermal phonon control in integrated circuits. They furthermore offer a practical implementation for the paradigms of acoustic metamaterials. The articles in this special issue illustrate several of these aspects.

Comptes Rendus Physique is an international journal of the French Academy of Sciences, published under the direction of Catherine Bréchignac.

The May 2016 issue is composed of 8 articles preceded by a foreword by the topical coordinator, Vincent Laude.
The special issue can be accessed online on Elsevier's website: http://www.sciencedirect.com/science/journal/aip/16310705
