Acoustic Metamaterial

Résumé

Over the past decade, electromagnetic metamaterials have shown tremendous potential in many disciplines of science and technology, and have led to a broad interest in devising techniques for manipulating different classes of waves with unconventional materials. Among them, acoustic metamaterials show the greatest promise for manipulating acoustic waves in a novel fashion for imaging, communication, detection and sound protection applications. Because of similar governing equations of electromagnetic waves and acoustic waves, which are the Maxwell equations and Helmholtz equations, respectively, the successes of metamaterials study in electromagnetic wave can be extended to the acoustic community. Permittivity and permeability of materials are used to describe electromagnetic wave properties, while acoustic wave properties are determined by the mass density and compressibility of materials.
