Elastic three-dimensional phononic topological insulators with Dirac hierarchy
Three-dimensional (3D) phononic topological insulators (TIs) featuring two-dimensional (2D) surface states and one-dimensional (1D) hinge states have opened up a new route for multi-dimensional robust wave tra...

Open AccessSimultaneous multi-band valley-protected topological edge states of shear vertical wave in two-dimensional phononic crystals with veins
The introduction of the concept of valley pseudospin to phononic crystals has made a remarkable topologically protected interface transport of sound, which opens a novel research area referred to as valley Hal...

Asymmetric propagation of the first order antisymmetric lamb wave in a tapered plate based on time domain analysis
The asymmetric propagation of the first order antisymmetric (A1) Lamb wave in a tapered plate respectively carved with sharp bottom corner and round bottom corner is theoretically investigated. Through numerical ...
