Abstract: A 1D unidirectional phononic waveguide embedded within a 3D hexagonal close‐packed (HCP) phononic crystal is investigated, formed through the introduction of a screw dislocation. This approach does not rely on the non‐trivial topological characteristics of… read more here.

Abstract: We consider an elastic helical medium whose tensor stiffness twirls uniformly along the helix axis. We are interested in analyzing the band structure when the whole material is externally forced to rotate around the helix… read more here.
