Journal ArticleDOI
Locally Resonant Sonic Materials
TL;DR: In this article, a 2-centimeter slab of this composite material is shown to break the conventional mass-density law of sound transmission by one or more orders of magnitude at 400 hertz.
Journal ArticleDOI
Locally resonant sonic materials
TL;DR: Sonic crystals are fabricated, based on the idea of localized resonant structures, that exhibit spectral gaps with a lattice constant two orders of magnitude smaller than the relevant wavelength that are shown to break the conventional mass-density law of sound transmission.
Journal ArticleDOI
Observation of topological valley transport of sound in sonic crystals
TL;DR: In this article, valley transport of sound is reported for a macroscopic triangular-lattice array of rod-like scatterers in a 2D air waveguide.
Journal ArticleDOI
Focusing of sound in a 3D phononic crystal.
TL;DR: Wave propagation was found to depend dramatically on both frequency and incident direction, which leads to very large negative refraction, which can be used to focus a diverging ultrasonic beam into a narrow focal spot with a large focal depth.
Journal ArticleDOI
Metamaterial with simultaneously negative bulk modulus and mass density.
TL;DR: A metamaterial which simultaneously possesses a negative bulk modulus and mass density is reported which is a zinc blende structure consisting of one fcc array of bubble-contained-water spheres and another relatively shifted fCC array of rubber-coated-gold spheres in epoxy matrix.
