“Deflecting elastic prism” and unidirectional localisation for waves in chiral elastic systems

Abstract For the first time, a design of a “deflecting elastic prism” is proposed and implemented for waves in a chiral medium. A novel model of an elastic lattice connected to a non-uniform system of gyroscopic spinners is designed to create a unidirectional wave pattern, which can be diverted by m...
