Focused electromagnetic doughnut pulses and their interaction with interfaces and nanostructures
T. A. Raybould, V. A. Fedotov, N. Papasimakis +2
We study the propagation properties and light-matter interactions of the focused doughnut pulses, broadband, single-cycle electromagnetic perturbations of toroidal topology first d…
Toroidal dipole excitations in metamolecules formed by interacting plasmonic nanorods
Derek W. Watson, Stewart D. Jenkins, Janne Ruostekoski +2
We show how the elusive toroidal dipole moment appears as a radiative excitation eigenmode in a metamolecule resonator that is formed by pairs of plasmonic nanorods. We analyze one…
Toroidal optical activity
T. A. Raybould, V. A. Fedotov, N. Papasimakis +5
Optical activity is ubiquitous across natural and artificial media and is conventionally understood in terms of scattering from electric and magnetic moments. Here we demonstrate e…
Wavevector Selective Metasurfaces and Tunnel Vision Filters
Vassili. A. Fedotov, Jan Wallauer, Markus Walther +3
Metasurfaces offer unprecedented flexibility in the design and control of light propagation, replacing bulk optical components and exhibiting exotic optical effects. One of the bas…
