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
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.
Journal ArticleDOI
Valley Vortex States in Sonic Crystals.
TL;DR: The acoustic version of valley states in sonic crystals are studied and a vortex nature of such states is revealed and the valley selection enables a handy way to create vortex matter in acoustics, in which the vortex chirality can be controlled flexibly.
Journal ArticleDOI
Anomalous refraction of airborne sound through ultrathin metasurfaces
TL;DR: An effective design of metasurface structures that can deflect the transmitted airborne sound in an anomalous way is presented, made of spatially varied coiling-slit subunits and has a thickness of deep subwavelength.

Highly efficient anomalous refraction of airborne sound through ultrathin metasurfaces
TL;DR: In this article, a flat lens, made of spatially varied coiling-slit subunits, has a thickness of deep subwavelength, which can deflect the transmitted airborne sound in an anomalous way.
