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…

Spring-loaded: Engineering Dispersion Relations Using Complex Couplings
R. G. Edge, S. A. R. Horsley, T. A. Starkey +1
Motivated by recent theoretical and experimental interest in metamaterials comprising non-local coupling terms, we present an analytic framework to realise materials with arbitrary…

Time Varying Resonators in Acoustic Waveguides: A Transfer Matrix Formalism for Space-time Modulated Metamaterials
D. Cidlinsky, G. J. Chaplain, S. A. R. Horsley
The transfer matrix method remains a simple yet powerful tool for modeling acoustic systems, particularly in a closed waveguide geometry. Here we present a generalisation of this m…
