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…
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…
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…
