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…
