Acoustic topological circuitry in square and rectangular phononic crystals
Nicolas Laforge, Richard Wiltshaw, Richard V. Craster +6
We systematically engineer a series of square and rectangular phononic crystals to create experimental realisations of complex topological phononic circuits. The exotic topological…
Hybrid topological guiding mechanisms for photonic crystal fibers
Mehul P. Makwana, Richard Wiltshaw, Sébastien Guenneau +1
We create hybrid topological-photonic localisation of light by introducing concepts from the field of topological matter to that of photonic crystal fiber arrays. S-polarized obliq…
Localising elastic edge waves via the topological rainbow effect
Bogdan Ungureanu, Mehul P. Makwana, Richard V. Craster +1
We combine two different fields, topological physics and graded metamaterials to design a topological metasurface to control and redirect elastic waves. We strategically design a t…
Asymptotic approximations for Bloch waves and topological mode steering in a planar array of Neumann scatterers
Richard Wiltshaw, Richard V. Craster, Mehul P. Makwana
We study the canonical problem of wave scattering by periodic arrays, either of infinite or finite extent, of Neumann scatterers in the plane; the characteristic lengthscale of the…
