Bound States to the Continuum: Time-varying Spoof Acoustic Surface Waves
E. Paul, G. J. Chaplain, J. Li +2
We develop a theoretical framework for time-modulated acoustic metasurfaces comprising a line array of modulated cavities, and show that bound acoustic surface waves can undergo te…

Discrete Euler-Bernoulli Beam Lattices with Beyond Nearest Connections
R. G. Edge, E. Paul, K. H. Madine +3
The propagation of elastic waves on discrete periodic Euler-Bernoulli mass-beam lattices is characterised by the competition between coupled translational and rotational degrees-of…
