Helicity-preserving optical cavity modes for enhanced sensing of chiral molecules
Joshua Feis, Dominik Beutel, Julian Köpfler +4
Researchers routinely sense molecules by their infrared vibrational "fingerprint" absorption resonances. In addition, the dominant handedness of chiral molecules can be detected by…

Achiral, Helicity Preserving, and Resonant Structures for Enhanced Sensing of Chiral Molecules
Florian Graf, Joshua Feis, Xavier Garcia-Santiago +3
We derive a set of design requirements that lead to structures suitable for molecular circular dichroism (CD) enhancement. Achirality of the structure and two suitably selected seq…

Surface Plasmon Polaritons Sustained at the Interface of a Nonlocal Metamaterial
Joshua Feis, Karim Mnasri, Andrii Khrabustovskyi +3
Studying basic physical effects sustained in metamaterials characterized by specific constitutive relation is a research topic with a long standing tradition. Besides intellectual…
