Localising elastic edge waves via the topological rainbow effect
Bogdan Ungureanu, Mehul P. Makwana, Richard V. Craster +1
We combine two different fields, topological physics and graded metamaterials to design a topological metasurface to control and redirect elastic waves. We strategically design a t…

Observations of symmetry induced topological mode steering in a reconfigurable elastic plate
Kun Tang, Mehul P. Makwana, Richard V. Craster +1
We experimentally investigate the valley-Hall effect for interfacial edge states, highlighting the importance of the modal patterns, between geometrically distinct regions within a…
