Reconfigurable topological valley-Hall interfaces: Asymptotics of arrays of Dirichlet and Neumann inclusions for multiple scattering in metamaterials
Richard Wiltshaw, Henry J. Putley, Christelle Bou Dagher +1
We study two-dimensional periodic metamaterials in which idealised cylindrical inclusions are modelled by boundary conditions. In the scalar time-harmonic setting, the background f…
Asymptotically exact photonic analogues of chiral symmetric topological tight-binding models
Samuel J Palmer, Yordan Ignatov, Richard V Craster +1
Topological photonic edge states, protected by chiral symmetry, are attractive for guiding wave energy as they can allow for more robust guiding and greater control of light than a…
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…
Novel topological beam-splitting in photonic crystals
Mehul P. Makwana, Richard Craster, Sebastien Guenneau
We create a passive wave splitter, created purely by geometry, to engineer three-way beam splitting in electromagnetism in transverse electric polarisation. We do so by considering…
