The influence of structure geometry and material on seismic metamaterial performance
T. Venkatesh Varma, Bogdan Ungureanu, Saikat Sarkar +3
Diverting, and controlling, elastic vibrations impacting upon infrastructure is a major challenge for seismic hazard mitigation, and for the reduction of machine noise and vehicle…
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…
Seismic wave shield using cubic arrays of split-ball resonators
Bogdan Ungureanu, Younes Achaoui, Stephane Brule +3
Metre size inertial resonators located in the ground have been theoretically shown to interact with a seismic wave (attenuation, band gaps) to enable protection of surface structur…
The influence of building interactions on seismic and elastic surface waves
Bogdan Ungureanu, Sébastien Guenneau, Younes Achaoui +6
We outline some recent research advances on the control of elastic waves in thin and thick plates, that have occurred since the large scale experiment [Phys. Rev. Lett. 112, 133901…
