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…
Tailored elastic surface to body wave Umklapp conversion
Gregory J. Chaplain, Jacopo M. De Ponti, Andrea Colombi +7
Elastic waves guided along surfaces dominate applications in geophysics, ultrasonic inspection, mechanical vibration, and surface acoustic wave devices; precise manipulation of sur…
