Pseudospins and topological edge states in elastic shear waves
We present a new framework to realize topological edge states in elastic shear waves in a two-dimensional (2D) phononic crystal (PC). The PC has a simple structure and is composed of a triangular array of core-shell cylinders embedded in an epoxy background. By tuning the geometrical parameters of t...
