Localized Topological States beyond Fano Resonances via Counter-Propagating Wave Mode Conversion in Piezoelectric Microelectromechanical Devices
Jacopo M. De Ponti, Xuanyi Zhao, Luca Iorio +6
A variety of scientific fields like proteomics and spintronics have created a new demand for on-chip devices capable of sensing parameters localized within a few tens of micrometer…
Edge-selective reconfiguration in polarized lattices with magnet-enabled bistability
Luca Iorio, Raffaele Ardito, Stefano Gonella
The signature topological feature of Maxwell lattices is their polarization, which manifests as an unbalance in stiffness between opposite edges of a finite domain. The manifestati…
Phononic graded meta-MEMS for elastic wave amplification and filtering
Federico Maspero, Jacopo Maria De Ponti, Luca Iorio +5
Inspired by recent graded metamaterials designs, we create phononic arrays of micro-resonators for frequency signal amplification and wave filtering. Leveraging suspended waveguide…
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…
Optimised graded metamaterials for mechanical energy confinement and amplification via reinforcement learning
Luca Rosafalco, Jacopo Maria De Ponti, Luca Iorio +2
A reinforcement learning approach to design optimised graded metamaterials for mechanical energy confinement and amplification is described. Through the proximal policy optimisatio…
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…
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…
