This inverse problem is implemented as a nonlinear regression-type optimization problem, in which the simulation signals are fitted to the measurement signals. These signals consist of displacement responses in waveguides, focusing on hollow cylindrical geometries to enhance the simulation efficiency. To accelerate the optimization and reduce the number of model evaluations and wait times, we propose two novel methods. First, we introduce an adaptation of the Levenberg–Marquardt method derived from a geometrical interpretation of the least-squares optimization problem. Second, we introduce an improved objective function based on the autocorrelated envelopes of the measurement and simulation signals. Given that this study primarily relies on simulation data to quantify optimization convergence, we aggregate the expected ranges of realistic material parameters and derive their distributions to ensure the reproducibility of optimizations with proper measurements. We demonstrate the effectiveness of our objective function modification and step adaptation for various materials with isotropic material symmetry by comparing them with the Broyden–Fletcher–Goldfarb–Shanno method. In all cases, our method reduces the total number of model evaluations, thereby shortening the time to identify the material parameters.","lang":"eng"}]},{"abstract":[{"text":"Light-emitting diodes (LEDs) are becoming increasingly important across various sectors of the lighting industry and are being used more frequently. In the field of symbolic projection, research is increasingly focusing on implementing light modulation using energy-efficient, incoherent LEDs rather than lasers. Since light modulation in micro- and nano-optics is typically achieved through phase modulation, Finite-Difference Time-Domain (FDTD) simulations are employed for analysis. The objective of this article is to investigate different approaches for approximating incoherent monochromatic light sources within FDTD simulations. To this end, two approaches based on dipole sources are considered, as well as a method involving plane waves with modulated wavefronts based on Cosine–Fourier functions and a method based on the superposition of Gaussian beams. These methods are evaluated in terms of their accuracy using a two-dimensional double-slit configuration and are compared against a fully incoherent analytical reference.","lang":"eng"}],"publication":"Photonics","language":[{"iso":"eng"}],"keyword":["tet_topic_opticalantenna","tet_topic_numerics","tet_topic_meta"],"year":"2026","issue":"2","quality_controlled":"1","title":"Approximating Incoherent Monochromatic Light Sources in FDTD Simulations","date_created":"2026-02-02T07:18:03Z","publisher":"MDPI AG","status":"public","type":"journal_article","article_number":"128","article_type":"original","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"},{"_id":"61"}],"user_id":"158","_id":"63827","intvolume":"        13","citation":{"mla":"Metzner, Dominik, et al. “Approximating Incoherent Monochromatic Light Sources in FDTD Simulations.” <i>Photonics</i>, vol. 13, no. 2, 128, MDPI AG, 2026, doi:<a href=\"https://doi.org/10.3390/photonics13020128\">10.3390/photonics13020128</a>.","bibtex":"@article{Metzner_Potthoff_Zentgraf_Förstner_2026, title={Approximating Incoherent Monochromatic Light Sources in FDTD Simulations}, volume={13}, DOI={<a href=\"https://doi.org/10.3390/photonics13020128\">10.3390/photonics13020128</a>}, number={2128}, journal={Photonics}, publisher={MDPI AG}, author={Metzner, Dominik and Potthoff, Jens and Zentgraf, Thomas and Förstner, Jens}, year={2026} }","short":"D.

We present a simple approach to synthesize phase-pure quasi-2D layered tin perovskite nanowires with varying quantum well thicknesses (n = 1 to 4). By incorporating a new organic spacer capable of forming a hydrogen-bonded organic framework, this method promoted anisotropic crystal growth and enhanced lattice rigidity. Furthermore, introducing molecular intercalants enabled controlled crystallization into well-defined nanowires that function as Fabry–Pérot cavities. Cavities made from n = 2 to 4 perovskites support efficient and robust near-infrared, room-temperature optically pumped lasing with the threshold as low as 75.8 μJ/cm2, cavity quality factor over 3000, and negligible degradation over 106 pulses.

To achieve their maximum mechanical properties, the fiber-matrix adhesion (FMA) is critical. In this work, continuous fiber-reinforced thermoplastic laminates (CFRTPL) with a polypropylene (PP) matrix and twill woven glass fiber fabrics are produced by film stacking. The films used contain different amounts of maleic-anhydride-grafted PP (MA-g-PP) as a coupling agent to produce CFRTPL of different mechanical strengths. To analyze the FMA, the CFRTPL are subjected to Charpy-impact and tensile tests. Additionally, single fiber pull-out tests (SFPT) are conducted to further investigate the effect of MA-g-PP on the FMA. The results of the SFPT show an improvement in apparent interfacial shear strength (AIFSS) when the MA-g-PP content is increased, which can be attributed to an increase in FMA. However, the research shows that MA-g-PP has a low impact on the mechanical properties if the force is applied parallel to the warp and weft threads during tensile testing and the results of the Charpy-impact testing suffer from embrittlement of the matrix material. Subsequently, the results of this study are compared to three-point flexural tests conducted in a previous study. It can be concluded that tensile and impact tests are not suited to investigate FMA on a macroscopic scale, while SFPT and flexural tests provide a better alternative.</jats:p>","lang":"eng"}],"publication":"International Polymer Processing","type":"journal_article","language":[{"iso":"eng"}],"department":[{"_id":"9"},{"_id":"321"},{"_id":"367"},{"_id":"34"},{"_id":"49"}],"user_id":"59363","_id":"65242","citation":{"bibtex":"@article{Moritzer_Brandes_Wittler_Claes_Wippermann_Haag_Gries_Henning_2026, title={Fiber-matrix adhesion in glass fiber reinforced thermoplastic composite laminates and its effect on mechanical properties}, DOI={<a href=\"https://doi.org/10.1515/ipp-2025-0077\">10.1515/ipp-2025-0077</a>}, journal={International Polymer Processing}, publisher={Walter de Gruyter GmbH}, author={Moritzer, Elmar and Brandes, Philipp and Wittler, Maurice and Claes, Leander and Wippermann, Mareen and Haag, Markus and Gries, Thomas and Henning, Bernd}, year={2026} }","short":"E.

Of paramount importance for the tailored mechanical properties these composite materials exhibit is the type and geometry of the fibre weave. Especially continuous fibre-reinforced thermoplastic composites are fabricated as laminates and subsequently exposed to forming processes which alter the geometry of the fibres unit cell and thus the local mechanical properties of the material. An approach utilising broadband ultrasonic waves is proposed to non-destructively determine the geometry of the unit cell of the weave.\r\n\r\nThe dispersive behaviour of woven fibre-reinforced sheets is described in accordance with the Flouquet-Bloch theorem as a phononic crystal. In order to develop a model for a description of these periodically structured waveguides, the smallest repeating unit of the wave is modelled with periodic boundary conditions. The resulting dispersion diagram exhibits similarities to that of a homogeneous plate, but additionally displays a periodicity in the wavenumber regime, which correspond with the size of the unit cell. Experimental studies of the dispersive behaviour of acoustic waves in woven fibre-reinforced samples also show a periodicity in the wavenumber regime, enabling a measurement procedure of the unit cell geometry.","lang":"eng"}],"user_id":"11829","department":[{"_id":"49"},{"_id":"147"}],"project":[{"_id":"157","name":"FaMOUS: Ein ultraschallbasiertes Messverfahren unter Berücksichtigung viskoelastischer Eigenschaften zur Charakterisierung der Faser-Matrix-Haftung bei Organoblechen sowie deren realitätsnahe Modellierung","grant_number":"495847374"}],"_id":"59683","language":[{"iso":"eng"}],"citation":{"mla":"Wippermann, Mareen, et al. <i>Determination of the Unit Cell Geometry in Fibre-Reinforced Polymer Sheets Using Guided Acoustic Waves</i>. 2025, doi:<a href=\"https://doi.org/10.71568/DASDAGA2025.116\">10.71568/DASDAGA2025.116</a>.","short":"M.

Conventionally, the input DC-link voltage is controlled to operate the LLC converter at resonance for the given operating point. However, the DC-link capacitor voltage shows a low-frequency voltage ripple (typically the second harmonic of grid frequency) in cascaded converters so that the LLC has to adapt its switching frequency within the grid period. Conventionally, the LLC converter operates 50% of the time above the resonant frequency of 40 kHz and 50% below resonance. Both operating conditions cause additional losses. However, experimental measurements indicate that the below-resonance operation causes significantly higher losses than above-resonance operation due to much higher primary and secondary transformer currents. It is better to increase the DC-link voltage by 30% of the peak-to-peak low-frequency voltage ripple to mostly avoid below-resonance operation (i.e., from 650 V to 680 V in this case). With the proposed control, the LLC converter operates about 75% of time over resonance and only 25% of time below resonance. The overall efficiency increases from 97.66% to 97.7% for the average operating point with an 80% load current. This corresponds to a 2% total loss reduction. Finally, the peak resonance capacitor voltage decreases from 910 V to 790 V (−13%).","lang":"eng"}],"publication":"Electronics","title":"Adaptive DC-Link Voltage Control for 22 kW, 40 kHz LLC Resonant Converter Considering Low-Frequency Voltage Ripple","date_created":"2025-05-05T12:27:39Z","publisher":"MDPI AG","year":"2025","issue":"8","article_number":"1517","department":[{"_id":"52"}],"user_id":"34289","_id":"59805","status":"public","type":"journal_article","doi":"10.3390/electronics14081517","main_file_link":[{"url":"https://www.mdpi.com/2079-9292/14/8/1517"}],"volume":14,"author":[{"full_name":"Unruh, Roland","id":"34289","last_name":"Unruh","first_name":"Roland"},{"first_name":"Joachim","id":"66","full_name":"Böcker, Joachim","last_name":"Böcker","orcid":"0000-0002-8480-7295"},{"first_name":"Frank","last_name":"Schafmeister","id":"71291","full_name":"Schafmeister, Frank"}],"date_updated":"2025-05-05T12:34:00Z","intvolume":"        14","citation":{"apa":"Unruh, R., Böcker, J., &#38; Schafmeister, F.
