Low PAPR OFDM Using SLM with Modified Riemann Matrix in JARC Systems

Didem Aydogan, Charles Tatkeu, Yassin El Hillali

Orthogonal Frequency Division Multiplexing (OFDM) is a promising technology for joint automotive radar and communication (JARC) systems operating in the 77–81 GHz band. While the Selective Mapping (SLM) technique effectively reduces the Peak-to-Average Power Ratio (PAPR) through phase sequence…

Studies on He and Ne gas permeation in microfabricated cells using Al2O3 coatings

Clément Carlé, Petri Karvinen, Shervin Keshavarzi, Samuel Queste, Moustafa Abdel Hafiz, Vincent Maurice, Rodolphe Boudot, Nicolas Passilly

The stability of cell-based atomic devices can be affected by the evolution of the cell inner atmosphere. The use of efficient gas permeation barriers is then of significant importance to enhance the performances of these instruments. In a recent study, we have demonstrated the reduction of helium…

Development of FETs based on ultra-wide band gap materials for high voltage power electronics, Développement de FET basés sur des matériaux à bande interdite ultra-large pour l'électronique de puissance haute tension

Jash Mehta

Wide Bandgap Semiconductors (WBG) such as SiC and GaN show superior material properties to Silicon. However, the even wider bandgap material or dielectric such as Aluminum Gallium Nitride (AlGaN) or Aluminium Nitride (AlN) material system gives the flexibility of creating heterojunctions while…, Les semi-conducteurs à large bande interdite (WBG) tels que le SiC et le GaN présentent des propriétés physiques supérieures à celles du silicium. Cependant, les matériaux ou diélectriques à bande interdite encore plus large, tels que le nitrure d'aluminium et de gallium (AlGaN) ou le nitrure…

Multicomponent organic blend systems: A review of quaternary organic photovoltaics

Kekeli N'Konou, Souk Kim, Nutifafa Doumon

Abstract Embedding a third and/or fourth component into a binary blend active layer of organic photovoltaics (OPVs) is a promising approach to achieve high‐performance photovoltaic cells and modules. This multicomponent strategy favors absorption broadening via additional components. Quaternary OPV…

Optical damage thresholds of single-mode fiber-tip spintronic terahertz emitters

Felix Paries, Felix Selz, Jean-Francois Lampin, Pierre Kolejak, Geoffrey Lezier, Nicolas Tiercelin, Mathias Vanwolleghem, Tobias Kampfrath, Tom Seifert, Georg von Freymann, Daniel Molter

Spintronic terahertz emitters (STEs) are gapless, ultrabroadband terahertz sources that can be driven within a wide pump-wavelength and repetition-rate range. While STEs driven by strong pump lasers operating at kilohertz repetition rates excel in generating high electric field strengths for…

State‐of‐the‐Art and Future Challenges of Smart Wound Dressings for Diabetic Foot Ulcer Treatment

Sabine Szunerits, Rabah Boukherroub

The slow healing process of diabetic wound due to persisting infections in wound bed, owing to hyperglycemia, makes the search for efficient treatments pending. While it is complicated to increase the wound closure rate in diabetic‐related wounds due to the complex pathology, the treatment of such…
