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…
Analytical solutions for Bloch waves in resonant phononic crystals: Deep subwavelength energy splitting and mode steering between topologically protected interfacial and edge states
Richard Wiltshaw, Jacopo Maria De Ponti, Richard Vaughan Craster
We derive analytical solutions based on singular Green's functions, which enable efficient computations of scattering simulations or Floquet-Bloch dispersion relations for waves pr…
A Graded Metamaterial for Broadband and High-capability Piezoelectric Energy Harvesting
Bao Zhao, Henrik R. Thomsen, Jacopo M. De Ponti +5
This work studies a broadband graded metamaterial, which integrates the piezoelectric energy harvesting function targeting low-frequency structural vibrations, lying below 100 Hz.…
Observation of Elastic Orbital Angular Momentum Transfer: Coupling Flexural Waves in Partially Submerged Pipes to Acoustic Waves in Fluids
G. J. Chaplain, J. M. De Ponti, T. A. Starkey
Research into the orbital angular momentum carried by helical wave-fronts has been dominated by the fields of electromagnetism and acoustics, owing to its practical utility in sens…
