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…
A Non-diffracting Resonant Angular Filter
Tristan. M. Lawrie, Gregor. Tanner, Gregory. J. Chaplain
We conceptualise and numerically simulate a resonant metamaterial interface incorporating non-local, or beyond nearest neighbour, coupling that acts as a discrete angular filter. I…
Acoustic Lattice Resonances and Generalised Rayleigh--Bloch Waves
G. J. Chaplain, S. C. Hawkins, M. A. Peter +2
The intrigue of waves on periodic lattices and gratings has resonated with physicists and mathematicians alike for decades. In-depth analysis has been devoted to the seemingly simp…
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…
Application of Quantum Graph Theory to Metamaterial Design: Negative Refraction of Acoustic Waveguide Modes
T. M. Lawrie, T. A. Starkey, G. Tanner +3
We leverage quantum graph theory to quickly and accurately characterise acoustic metamaterials comprising networks of interconnected pipes. Anisotropic bond lengths are incorporate…
