Journal ArticleDOI
Achiral, Helicity Preserving, and Resonant Structures for Enhanced Sensing of Chiral Molecules
Florian Graf,Joshua Feis,Xavier Garcia-Santiago,Martin Wegener,Carsten Rockstuhl,Ivan Fernandez-Corbaton +5 more
TL;DR: In this article, the authors derive a set of design requirements that lead to structures suitable for molecular circular dichroism (CD) enhancement, and design an exemplary structure following the requirements. But the considered system is a planar array of silicon cylinders under normally incident plane-wave illumination.
Journal ArticleDOI
Helicity-Preserving Optical Cavity Modes for Enhanced Sensing of Chiral Molecules
Joshua Feis,Dominik Beutel,Julian Köpfler,Xavier Garcia-Santiago,Carsten Rockstuhl,Martin Wegener,Ivan Fernandez-Corbaton +6 more
TL;DR: In this paper, a cavity composed of two parallel arrays of helicity-preserving silicon disks is proposed to enhance the dominant handedness of chiral molecules by circular dichroism (CD), the normalized difference between their optical response to incident left and right-handed circularly polarized light.

Journal ArticleDOI
Wireless power transfer through asymmetric topological edge states in diatomic chains of coupled meta-atoms
TL;DR: In this article, the authors present a different perspective on wireless power transfer by uniting topological edge states, which are robust states on the edge of a material enforced by topological invariants, with magnetoinductive waves on a 1D diatomic chain of magnetically coupled meta-atoms with intracell coupling exceeding intercell coupling.
Journal ArticleDOI
Surface plasmon polaritons sustained at the interface of a nonlocal metamaterial
Joshua Feis,Karim Mnasri,Andrii Khrabustovskyi,Christian Stohrer,Michael Plum,Carsten Rockstuhl +5 more
TL;DR: In this article, the impact of non-local dispersion on the dispersion relation of surface plasmon polaritons sustained at an interface between vacuum and a metamaterial is investigated.
