Abstract

In this work, we study locally resonant acoustic chains with inerters. Topological properties are investigated on the exampleof one-dimensional chain with diatomic mass-in-mass unit cells based on the band structure and eigenstate analysis. The existence ofinterface modes in finite chains is confirm...
