Higher-order topology in plasmonic kagome lattices
Matthew Proctor, María Blanco de Paz, Dario Bercioux +2
We study the topological properties of a kagome plasmonic metasurface, modelled with a coupled dipole method which naturally includes retarded long range interactions. We demonstra…
Homogenisation Theory of Space-Time Metamaterials
Paloma Arroyo Huidobro, Mario G. Silveirinha, Emanuele Galiffi +1
We present a general framework for the homogenisation theory of space-time metamaterials. By mapping to a frame co-moving with the space-time modulation, we derive analytical formu…
A new mechanism for gain in time dependent media
J. B. Pendry, E. Galiffi, P. A. Huidobro
Time dependent systems do not in general conserve energy invalidating much of the theory developed for static systems and turning our intuition on its head. This is particularly ac…
On the robustness of topological corner modes in photonic crystals
Matthew Proctor, Paloma Arroyo Huidobro, Barry Bradlyn +4
We analyze the robustness of corner modes in topological photonic crystals, taking a -symmetric breathing honeycomb photonic crystal as an example. First, we employ topologica…
Wood Anomalies and Surface-Wave Excitation with a Time-Grating
Emanuele Galiffi, Yao-Ting Wang, Zhen Lim +3
In order to confine waves beyond the diffraction limit, advances in fabrication techniques have enabled subwavelength structuring of matter, achieving near-field control of light a…
