On the Practicability of Ceramic-Tiled Walls for Sound Absorption by Tuning Cavities
Ozgur T. Tugut, Brahim Lemkalli, Qingxiang Ji +7
We present the practicality of structuring ceramic tiles for enhancing sound absorption on rigid walls. The cornerstone of our methodology is to structure walls with cavities so th…
Controlling the Propagation of Flexural Elastic Waves With Ceramic Metatiles
Brahim Lemkalli, Ozgur T. Tugut, Qingxiang Ji +5
In this work, we examine the application of phononic metamaterials for elastic impact noise insulation in tiled flooring, through the development of an innovative ceramic metatile…
Neolithic stone settlements as locally resonant metasurfaces
Stéphane Brûlé, Bogdan Ungureanu, Stefan Enoch +1
We study the dynamic surface response of neolithic stone settlements obtained with seismic ambient noise techniques near the city of Carnac in French Brittany. Surprisingly, we fin…
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…
