Experimental observation of temporal pumping in electro-mechanical waveguides
Yiwei Xia, Emanuele Riva, Matheus I. N. Rosa +4
We experimentally demonstrate temporal pumping of elastic waves in an electromechanical waveguide. An aluminum beam covered by an array of piezoelectric patches connected to shunt…
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…
Adiabatic pumping via avoided crossings in stiffness modulated quasiperiodic beams
Emanuele Riva, Vito Casieri, Ferruccio Resta +1
In this manuscript we report on adiabatic pumping in quasiperiodic stiffness modulated beams. We show that distinct topological states populating nontrivial gaps can nucleate avoid…
