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…
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…
Closed form expressions for the Green's function of a quantum graph -- a scattering approach
Tristan Lawrie, Sven Gnutzmann, Gregor Tanner
In this work we present a three step procedure for generating a closed form expression of the Green's function on both closed and open finite quantum graphs with general self-adjoi…
