Topological rainbow trapping for elastic energy harvesting in graded SSH systems
Gregory J. Chaplain, Jacopo M. De Ponti, Giulia Aguzzi +2
We amalgamate two fundamental designs from distinct areas of wave control in physics, and place them in the setting of elasticity. Graded elastic metasurfaces, so-called metawedges…
Experimental investigation of amplification, via a mechanical delay-line, in a rainbow-based metasurface for energy harvesting
Jacopo M. De Ponti, Andrea Colombi, Emanuele Riva +4
We demonstrate that a rainbow-based metasurface, created by a graded array of resonant rods attached to an elastic beam, operates as a mechanical delay-line by slowing down surface…
Rainbow reflection and trapping for energy harvesting
Gregory J. Chaplain, Daniel Pajer, Jacopo M. De Ponti +1
Important distinctions are made between two related wave control mechanisms that act to spatially separate frequency components; these so-called rainbow mechanisms either slow or r…
Graded metasurface for enhanced sensing and energy harvesting
Jacopo M. De Ponti, Andrea Colombi, Raffaele Ardito +3
In elastic wave systems, combining the powerful concepts of resonance and spatial grading within structured surface arrays enable resonant metasurfaces to exhibit broadband wave fo…
