WebOct 4, 2024 · In this work, we analyze the transport properties of acoustic waves in one-dimensional phononic materials constituted of either non-resonant or resonant scatterers distributed along stealthy hyperuniform patterns in air. A phononic crystal is an artificial and periodic structure that supports the propagation of mechanical waves. By artificial, we refer to its technological fabrication process, by a human or a machine, at almost any available scale.
