Bandgap widening and resonating mass reduction through wave locking
Luca Iorio, Jacopo M. De Ponti, Alberto Corigliano +1
Elastic metamaterials made from locally resonant arrays have been developed as effective ways to create band gaps for elastic or acoustic travelling waves. They work by implementin…
Roton-like dispersion via polarisation change for elastic wave energy control in graded delay-lines
Luca Iorio, Jacopo Maria De Ponti, Federico Maspero +1
While roton dispersion relations had been restricted to correlated quantum systems at low temperature, recent works show the possibility of obtaining this unusual dispersion in aco…
Tailored Topological Edge Waves via Chiral Hierarchical Metamaterials
Jacopo M. De Ponti, Luca Iorio, Gregory J. Chaplain +3
Precise manipulation of the direction and re-direction of vibrational wave energy is a key demand in wave physics and engineering. We consider the paradigm of a finite frame-like s…
Elastic three-dimensional metaframe for selective wave filtering and polarization control
Jacopo M. De Ponti, Emanuele Riva, Francesco Braghin +1
We experimentally achieve selective wave filtering and polarization control in a three-dimensional elastic frame embedding local resonators. By connecting multi-resonating elements…
Selective mode conversion and rainbow trapping via graded elastic waveguides
Jacopo M. De Ponti, Luca Iorio, Emanuele Riva +3
We experimentally achieve wave mode conversion and rainbow trapping in an elastic waveguide loaded with an array of resonators. Rainbow trapping is a phenomenon that induces wave c…
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…
