Cloaking via mapping for the heat equation
Richard Craster, Sebastien Guenneau, Harsha Hutridurga +1
This paper explores the concept of near-cloaking in the context of time-dependent heat propagation. We show that after the lapse of a certain threshold time instance, the boundary…
Asymptotic network models of subwavelength metamaterials formed by closely packed photonic and phononic crystals
Alice L. Vanel, Ory Schnitzer, Richard V. Craster
We demonstrate that photonic and phononic crystals consisting of closely spaced inclusions constitute a versatile class of subwavelength metamaterials. Intuitively, the voids and n…
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…
