Abstract :
We review our recent achievements in the development of metamaterials with mechanical nonlinearity. The novel nonlinearity types are achieved by enabling new degrees of freedom in metamaterial design, which allow a dynamic changes in the geometry of “meta-atoms” or in the lattice structure. We present the outcomes of magnetoelastic, conformational, rotational and optical nonlinear feedback, and predict unusual phenomena to be observed in such metamaterials.
