High-order homogenisation of the time-modulated wave equation: non-reciprocity for a single varying parameter
Marie Touboul, Bruno Lombard, Raphaël Assier +2
Laminated media with material properties modulated in space and time in the form of travelling waves have long been known to exhibit non-reciprocity. However, when using the method…
Active cloaking for clusters of pins in thin plates
Jane O'Neill, Ozgur Selsil, Stewart Haslinger +2
This paper considers active cloaking of a square array of evenly spaced pins in a Kirchhoff plate in the presence of flexural waves. Active sources are distributed exterior to the…
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…
Radiation from structured-ring resonators
B. Maling, O. Schnitzer, R. V. Craster
We investigate the scalar-wave resonances of systems composed of identical Neumann-type inclusions arranged periodically around a circular ring. Drawing on natural similarities wit…
High frequency homogenisation for elastic lattices
D. J. Colquitt, R. V. Craster, M. Makwana
A complete methodology, based on a two-scale asymptotic approach, that enables the homogenisation of elastic lattices at non-zero frequencies is developed. Elastic lattices are dis…
