Wave propagation in one-dimensional nonlinear acoustic metamaterials

Wave propagation in one-dimensional nonlinear acoustic metamaterials

The propagation of waves in nonlinear acoustic metamaterial (NAM) is fundamentally different from that in conventional linear ones. In this article we consider two one-dimensional (1D) NAM systems featuring respectively a diatomic and a tetratomic meta unit-cell. We investigate the attenuation of wa...
