摘 要:Controlling how waves propagate, attenuate and amplify in simple, scalable geometric structures is a daunting challenge for science and technology. In this talk, I will discuss how non-reciprocity can be used to steer mechanical waves in unprecedented ways. Combining experiments on active mechanical metamaterials with wave physics and continuum and topological mechanics, I will discuss the emergence of the non-Hermitian skin effect, of non-Hermitian topological waves and of unidirectional solitons. I will further show how these odd waves can be used to induce locomotion and unusual responses to impacts and hence pave the way towards a novel generation of robots.
