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…
Elastic Orbital Angular Momentum
G. J. Chaplain, J. M. De Ponti, R. V. Craster
We identify that flexural guided elastic waves in elastic pipes carry a well-defined orbital angular momentum associated with the compressional dilatational potential. This enables…
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…
