Dynamic Green's functions in discrete flexural systems
K. H. Madine, D. J. Colquitt
The paper presents an analysis of the dynamic behaviour of discrete flexural systems composed of Euler--Bernoulli beams. The canonical object of study is the discrete Green's funct…
An asymptotic hyperbolic-elliptic model for flexural-seismic metasurfaces
P. T. Wootton, J. Kaplunov, D. J. Colquitt
We consider a periodic array of resonators, formed from Euler-Bernoulli beams, attached to the surface of an elastic half-space. Earlier studies of such systems have concentrated o…
Elastic wave control beyond band-gaps: shaping the flow of waves in plates and half-spaces
Andrea Colombi, Richard Craster, Daniel Colquitt +4
It is well known in metamaterials that local resonance and hybridization phenomena dramatically influence the shape of dispersion curves; the metasurface created by a cluster of re…
Fluid-loaded metasurfaces
E. A. Skelton, R. V. Craster, A. Colombi +1
We consider wave propagation along fluid-loaded structures which take the form of an elastic plate augmented by an array of resonators forming a metasurface, that is, a surface str…
Enhanced sensing and conversion of ultrasonic Rayleigh waves by elastic metasurfaces
Andrea Colombi, Victoria Ageeva, Richard J. Smith +7
Recent years have heralded the introduction of metasurfaces that advantageously combine the vision of sub- wavelength wave manipulation, with the design, fabrication and size advan…
Seismic metasurfaces: Sub-wavelength resonators and Rayleigh wave interaction
D. J. Colquitt, A. Colombi, R. V. Craster +2
We consider the canonical problem of an array of rods, which act as resonators, placed on an elastic substrate; the substrate being either a thin elastic plate or an elastic half-s…
