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…
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…
Elastic three-dimensional metaframe for selective wave filtering and polarization control
Jacopo M. De Ponti, Emanuele Riva, Francesco Braghin +1
We experimentally achieve selective wave filtering and polarization control in a three-dimensional elastic frame embedding local resonators. By connecting multi-resonating elements…
The Elastic Spiral Phase Pipe
Gregory J. Chaplain, Jacopo M. De Ponti
We design a device for the passive mode conversion of guided, axisymmetric, ultrasonic waves in hollow elastic pipes into arbitrary non-axisymmetric flexural waves that have a cons…
