Enhanced broadband low-frequency performance of negative Poisson’s ratio metamaterials with added mass [PDF]
Scientific ReportsIn 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.

Tunable Negative Poisson’s Ratio in Van der Waals Superlattice [PDF]
Research, 2021 Negative Poisson’s ratio (NPR) materials are functional and mechanical metamaterials that shrink (expand) longitudinally after being compressed (stretched) laterally. By using first-principles calculations, we found that Poisson’s ratio can be tuned from
