40 GHz Beam-Steering Two-Elements Array Antenna Using GaN Varactors for Millimeter-Wave Applications

Abdelaziz Hamdoun, Farid Medjdoub, Mohamed Himdi, Olivier Lafond, Malek Zegaoui

A continuously steerable beam patch antenna array employing a classical phase shifter based on GaN HEMTs is presented. Here the GaN HEMTs are used as varactor diodes to achieve the tunability purpose. By controlling the DC bias of these varactors from -2 V to 2 V, the proposed…

Growth of Low-Temperature Epitaxial Lithium Niobate Thin Films and Guided-Wave Optical Properties

Thanh Ngoc Kim Bui, Estelle Wagner, Rahma Moalla, William Maudez, Karim Dogheche, Romain Bachelet, Bruno Masenelli, Giacomo Benvenuti, Denis Remiens, El Hadj Dogheche

LiNbO3 thin films are grown on a c-plane (0001) sapphire wafer at a relatively low substrate temperature by chemical beam vapor deposition (CBVD) in Sybilla equipment. Raman measurements only evidence the LiNbO3 phase, while HR-XRD diffractograms demonstrate a c-axis-oriented growth with only (006…

120 Gbit/s aggregated channel transmission in the 600 GHz band using topological waveguide

A.S. Mohammed, Gaëtan Lévêque, Edouard Lebouvier, Yan Pennec, Marc Faucher, Alberto Amo, Pascal Szriftgiser, T. Nagatsuma, Guillaume Ducournau

In this paper, we demonstrate a THz 3x40 Gbit/s data transmission within the 600 GHz band. Bit-error-rate performance is compliant with standard error-correction techniques limits, setting building blocks for THz communications in the 600 GHz region. The transmission is realized through a silicon…

Carbon Nanotube Based Waveguide and Application to Digital Communication in mmW Band

Rong Tao Jiang, Chong Wei Tan, Xing Hai Zhao, Stéphane Bila, Dominique Baillargeat, Philippe Coquet, Beng Kang Tay, Pascal Szriftgiser, Guillaume Ducournau

As the exploration of higher frequencies extends into Millimeter-wave (mmW) band and beyond, the hollow rectangular waveguide (HRWG) emerges as an increasingly attractive interconnect option due to its low-loss air medium, isolated propagation environment, and high-power handling capability.…

Aggregated 0.3 Tbit/s link using Photonics-transmitter and micromachined flat array antenna over 315-410 GHz

Hadjer Nihel Khelil, Alexandre Renau, Pascal Szriftgiser, Yannick Roelens, Rédha Kassi, Mohammed Zaknoune, Malek Zegaoui, Joachim Oberhammer, Guillaume Ducournau

This paper presents the validation of a wireless communication link in the THz range using a photonics-based transmitter and a waveguide-fed micromachined wideband flat array antenna. Combining several carrier frequencies over the 320-400 GHz band, we show that the antenna can handle an aggregated…

Nanoparticules organiques pour le ciblage des cellules β pancréatiques dans le diabète de type 1 et de type 2, Organic nanoparticles for targeting pancreatic β cells in type 1 and type 2 diabetes

Shakila Behzadifar

Le diabète pourrait concerner jusqu’à 642 millions de personnes dans le monde d’ici 2040. Le diabète de type 1 (DT1) se caractérise par une destruction progressive des cellules β (BCM) du pancréas par une réaction auto-immune. La BCM est alors réduite à 10-50 % au moment du diagnostic, puis…, Diabetes could affect up to 642 million people worldwide by 2040. Type 1 diabetes (T1D) is characterized by the progressive destruction of pancreatic β cells (PBCs) by an autoimmune reaction. PBCs are reduced to 10-50% at the time of diagnosis and continue to decline thereafter. In type 2 diabetes…
