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…
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…
