Fabry-Pérot ultrasonic metamaterials have been additively manufactured using laser powder bed fusion to contain subwavelength holes with a high aspect-ratio of width to depth. Such metamaterials require the acoustic impedance mismatch between the st

Phononic crystals are acoustic metamaterials designed to manipulate sound when its wavelength is in the order of magnitude of the crystal lattice constant. Metallic phononic crystals for use in water were assembled using commercially available stainl

Metamaterials exhibit properties beyond those exhibited by conventional materials in conventional scenarios. These have been investigated both theoretically and experimentally at length. In many cases the underpinning physical understanding of metama
