Localized Topological States beyond Fano Resonances via Counter-Propagating Wave Mode Conversion in Piezoelectric Microelectromechanical Devices
Jacopo M. De Ponti, Xuanyi Zhao, Luca Iorio +6
A variety of scientific fields like proteomics and spintronics have created a new demand for on-chip devices capable of sensing parameters localized within a few tens of micrometer…
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…
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…
