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…
Tunable topological edge modes in Su-Schrieffer-Heeger arrays
G. J. Chaplain, A. S. Gliozzi, B. Davies +4
A potential weakness of topological waveguides is that they act on a fixed narrow band of frequencies. However, by 3D printing samples from a photo-responsive polymer, we can obtai…
