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…
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…
