Enhanced broadband low-frequency performance of negative Poisson’s ratio metamaterials with added mass

Abstract In this work, we propose a negative Poisson’s ratio metamaterial with added mass (NPM). Introducing added mass induces the emergence of new bandgaps, effectively reducing the bandgap frequency and widening its width. Simulation results show that added mass can generate new low-frequency ban...
