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…
