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…
