we investigated theoretical aspects and experimentally tested a topological pump for elastic waves. Specifically, leveraging sinusoidally and square wave modulated plates, which are characterized by topological edge modes. When the modulation phase is adiabatically varied along one direction, the edge mode migrates from one boundary to the other, thus achieving a topological pump.

Abstract
we investigated theoretical aspects and experimentally tested a topological pump for elastic waves. Specifically, leveraging sinusoidally and square wave modulated plates, which are characterized by topological edge modes. When the modulation phase is adiabatically varied along one direction, the edge mode migrates from one boundary to the other, thus achieving a topological pump.File in questo prodotto:
