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…
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…
Experimental investigation of amplification, via a mechanical delay-line, in a rainbow-based metasurface for energy harvesting
Jacopo M. De Ponti, Andrea Colombi, Emanuele Riva +4
We demonstrate that a rainbow-based metasurface, created by a graded array of resonant rods attached to an elastic beam, operates as a mechanical delay-line by slowing down surface…
