Multipolar Pseudochirality Induced Optical Torque
Karim Achouri, Mintae Chung, Andrei Kiselev +1
It has been observed that achiral nano-particles, such as flat helices, may be subjected to an optical torque even when illuminated by normally incident linearly polarized light. H…
Demonstration of a plasmonic nonlinear pseudo-diode
Sergejs Boroviks, Andrei Kiselev, Karim Achouri +1
We demonstrate a nonlinear plasmonic metasurface that exhibits strongly asymmetric second-harmonic generation: nonlinear scattering is efficient upon excitation in one direction an…
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…
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…
Multipolar scattering analysis of hybrid metal-dielectric nanostructures
Debdatta Ray, Andrei Kiselev, Olivier J. F. Martin
We perform a systematic study showing the evolution of the multipoles along with the spectra for a hybrid metal-dielectric nanoantenna, a Si cylinder and an Ag disk stacked one on…
Multipolar Origin of the Unexpected Transverse Force Resulting from Two-Wave Interference
Karim Achouri, Andrei Kiselev, Olivier J. F. Martin
We propose a theoretical study on the electromagnetic forces resulting from the superposition of a TE and TM plane waves interacting with a sphere. Specifically, we first show that…
