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…
Edge States and Topological Pumping in Stiffness Modulated Elastic Plates
Emanuele Riva, Matheus I. N. Rosa, Massimo Ruzzene
We demonstrate that modulations of the stiffness properties of an elastic plate along a spatial dimension induce edge states spanning non-trivial gaps characterized by integer valu…
Experimental observation of non-reciprocal band-gaps in a space-time modulated beam using a shunted piezoelectric array
Jacopo Marconi, Emanuele Riva, Matteo Di Ronco +3
In this work we experimentally achieve 1 kHz-wide directional band-gaps for elastic waves spanning a frequency range from approximately 8 to 11 kHz. One-way propagation is induced…
Non-reciprocal wave propagation in discretely modulated spatiotemporal plates
Emanuele Riva, Matteo Di Ronco, Gabriele Cazzulani +1
We investigate non-reciprocal wave propagation in spatiotemporal phononic plates. In particular, the first goal of this manuscript is to present a general formulation of the Plane…
