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…
