Mind the gap between theory and experiment
Andrei Kiselev, Jeonghyeon Kim, Olivier J. F. Martin
We discuss some examples where numerical simulations based on effectively fabricated nanostructures can provide additional insights into an experiment. Focusing on plasmonics, we s…
Spatial Symmetries in Multipolar Metasurfaces: From Asymmetric Angular Transmittance to Multipolar Extrinsic Chirality
Karim Achouri, Ville Tiukuvaara, Olivier J. F. Martin
We propose a framework that connects the spatial symmetries of a metasurface to its material parameter tensors and its scattering matrix. This provides a simple yet effective way t…
Multipolar expansions for scattering and optical force calculations beyond the long wavelength approximation
Marco Riccardi, Andrei Kiselev, Karim Achouri +1
We review three different approaches for the calculation of electromagnetic multipoles, namely the Cartesian primitive multipoles, the Cartesian irreducible multipoles and the sphe…
Probing surfactant bilayer interactions by tracking optically trapped single nanoparticles
Jeonghyeon Kim, Olivier J. F. Martin
Single-particle tracking and optical tweezers are powerful techniques for studying diverse processes at the microscopic scale. The stochastic behavior of a microscopically observab…
Crossing of the branch cut: the topological origin of a universal 2π-phase retardation in non-Hermitian metasurfaces
Rémi Colom, Elena Mikheeva, Karim Achouri +5
Full wavefront control by photonic components requires that the spatial phase modulation on an incoming optical beam ranges from 0 to 2π. Because of their radiative coupling to the…
