Locally Enhanced and Tunable Optical Chirality in Helical Metamaterials
Philipp Gutsche, Raquel Mäusle, Sven Burger
We report on a numerical study of optical chirality. Intertwined gold helices illuminated with plane waves concentrate right and left circularly polarized electromagnetic field ene…
Time-Harmonic Optical Chirality in Inhomogeneous Space
Philipp Gutsche, Lisa V. Poulikakos, Martin Hammerschmidt +2
Optical chirality has been recently suggested to complement the physically relevant conserved quantities of the well-known Maxwell's equations. This time-even pseudoscalar is expec…
Method for fast computation of angular light scattering spectra from 2D periodic arrays
J. Pomplun, S. Burger, L. Zschiedrich +2
An efficient numerical method for computing angle-resolved light scattering off periodic arrays is presented. The method combines finite-element discretization with a Schur complem…
The Optical Chirality Flux as a Useful Far-Field Probe of Chiral Near Fields
Lisa V. Poulikakos, Philipp Gutsche, Kevin M. McPeak +4
To optimize the interaction between chiral matter and highly twisted light, quantities that can help characterize chiral electromagnetic fields near nanostructures are needed. Here…
