Abstract: 
In this work, we study locally resonant acoustic chains with inerters. Topological properties are investigated on the example of one-dimensional chain with diatomic mass-in-mass unit cells based on the band structure and eigenstate analysis. The existence of interface modes in finite chains is confirmed through natural frequencies and frequency response function analysis. Tuning of interface modes due to introduced inertia amplification effect is observed and investigated in details.
