T-matrix representation of optical scattering response: Suggestion for a data format
Nigar Asadova, Karim Achouri, Kristian Arjas +39
The transition matrix, frequently abbreviated as T-matrix, contains the complete information in a linear approximation of how a spatially localized object scatters an incident fiel…
Polarization-dependent effects in vibrational absorption spectra of 2D finite-size adsorbate islands on dielectric substrates
Benedikt Zerulla, Marjan Krstić, Shuang Chen +9
In the last years, Infrared Reflection-Absorption Spectroscopy (IRRAS) became a standard technique to study vibrational excitations of molecules. These investigations are strongly…
treams -- A T-matrix scattering code for nanophotonic computations
Dominik Beutel, Ivan Fernandez-Corbaton, Carsten Rockstuhl
We report the publication of treams, a new software for electromagnetic scattering computations based on the T-matrix method. Besides conventional T-matrix calculations for individ…
A Multi-Scale Approach to Simulate the Nonlinear Optical Response of Molecular Nanomaterials
Benedikt Zerulla, Dominik Beutel, Christof Holzer +3
Nonlinear optics is essential for many recent photonic technologies. Here, we introduce a novel multi-scale approach to simulate the nonlinear optical response of molecular nanomat…
Inverse Design of All-dielectric Metasurfaces with Bound States in the Continuum
Sergei Gladyshev, Theodosios D. Karamanos, Lina Kuhn +4
Metasurfaces with bound states in the continuum (BICs) have proven to be a powerful platform for drastically enhancing light-matter interactions, improving biosensing, and precisel…
Exploring Functional Photonic Devices made from a Chiral Metal-Organic Framework Material by a Multiscale Computational Method
Benedikt Zerulla, Chun Li, Dominik Beutel +9
Electronic circular dichroism is an important optical phenomenon offering insights into chiral molecular materials. On the other hand, metal-organic frameworks (MOFs) are a novel g…
A T-matrix Based Approach to Homogenize Artificial Materials
Benedikt Zerulla, Ramakrishna Venkitakrishnan, Dominik Beutel +4
The accurate and efficient computation of the electromagnetic response of objects made from artificial materials is crucial for designing photonic functionalities and interpreting…
Lattice Sums Accommodating Multiple Sublattices for Solutions of the Helmholtz Equation in Two and Three Dimensions
Dominik Beutel, Ivan Fernandez-Corbaton, Carsten Rockstuhl
The evaluation of the interaction between objects arranged on a lattice requires the computation of lattice sums. A scenario frequently encountered are systems governed by the Helm…
A Comprehensive Multipolar Theory for Periodic Metasurfaces
Aso Rahimzadegan, Theodosios D. Karamanos, Rasoul Alaee +4
Optical metasurfaces consist of a 2D arrangement of scatterers, and they control the amplitude, phase, and polarization of an incidence field on demand. Optical metasurfaces are th…
On enhanced sensing of chiral molecules in optical cavities
Philip Scott, Xavier Garcia-Santiago, Dominik Beutel +3
The differential response of chiral molecules to incident left- and right- handed circularly polarized light is used for sensing the handedness of molecules. Currently, significant…
Efficient simulation of bi-periodic, layered structures based on the T-matrix method
Dominik Beutel, Achim Groner, Carsten Rockstuhl +1
Predicting the optical response of macroscopic arrangements of individual scatterers is a computational challenge, as the problem involves length scales across multiple orders of m…
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…
