An acoustic metamaterial, sonic crystal, or phononic crystal, is a material designed to control, direct, and manipulate sound waves or phonons in gases, liquids, and solids (crystal lattices). Sound wave control is accomplished through manipulating parameters such as the bulk modulus β, density ρ, and chirality. … See more Acoustic metamaterials have developed from the research and findings in metamaterials. A novel material was originally proposed by Victor Veselago in 1967, but not realized until some 33 years later.
