Graded quasiperiodic metamaterials perform fractal rainbow trapping
Bryn Davies, Gregory J. Chaplain, Timothy A. Starkey +1
The rainbow trapping phenomenon of graded metamaterials can be combined with the fractal spectra of quasiperiodic waveguides to give a metamaterial that performs fractal rainbow tr…
Acoustic surface modes on metasurfaces with embedded next-nearest neighbor coupling
D. B. Moore, J. R. Sambles, A. P. Hibbins +2
We design, simulate, and experimentally characterize an acoustic metasurface comprising of a 1D array of open, sound-hard, cavities, modulated with beyond-nearest-neighbor (BNN) co…
Reconfigurable Elastic Metamaterials: Engineering Dispersion with Meccano
G. J. Chaplain, I. R. Hooper, A. P. Hibbins +1
We design, simulate and experimentally characterise a reconfigurable elastic metamaterial with beyond-nearest-neighbour (BNN) coupling. The structure is composed from the popular B…
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…
Underwater Focussing of Sound by Umklapp Diffraction
Gregory J. Chaplain, Richard V. Craster, Nick Cole +2
Scholte modes that are localized between a submerged axisymmetric-structured elastic plate and surrounding fluid can undergo mode conversion via Umklapp diffraction into radiative…
