Analytical and Numerical Analysis of Linear and Nonlinear Properties of an rf-SQUID Based Metasurface
Marvin M. Müller, Bernhard Maier, Carsten Rockstuhl +1
We derive a model to describe the interaction of an rf-SQUID (radio frequency superconducting quantum interference device) based metasurface with free space electromagnetic waves.…
Second Quantization of Scattering Modes of Absorptive Photonic Nanostructures
Jens Oppermann, Jakob Straubel, Karolina Słowik +1
We present a quantization scheme for optical systems with absorptive losses, based on an expansion in the complete set of scattering solutions to Maxwell's equations. The natural e…
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…
Benchmarking five global optimization approaches for nano-optical shape optimization and parameter reconstruction
Philipp-Immanuel Schneider, Xavier Garcia Santiago, Victor Soltwisch +3
Numerical optimization is an important tool in the field of computational physics in general and in nano-optics in specific. It has attracted attention with the increase in complex…
Perturbing beyond the shallow amplitude regime: Green's function scattering formalism with Bloch modes
A. Abass, A. Martins, S. Nanz +3
We present a Bloch modes' based Green's function scattering formalism for cost efficient forward modelling of disordered binary surface textures. The usage of Bloch modes of an unp…
Decomposition of scattered electromagnetic fields into vector spherical wave functions on surfaces with general shapes
Xavier Garcia-Santiago, Martin Hammerschmidt, Sven Burger +3
Decomposing the field scattered by an object into vector spherical harmonics (VSH) is the prime task when discussing its optical properties on more analytical grounds. Thus far, it…
