High gain/bandwidth off-chip antenna loaded with metamaterial unit-cell impedance matching circuit for sub-terahertz near-field electronic systems

Mohammad Alibakhshikenari, Bal Virdee, Dion Mariyanayagam, Valeria Vadalà, Mohammad Naser-Moghadasi, Chan See, Iyad Dayoub, Sonia Aïssa, Patrizia Livreri, Shah Nawaz Burokur, Anna Pietrenko-Dabrowska, Francisco Falcone, Slawomir Koziel, Ernesto Limiti

An innovative off-chip antenna (OCA) is presented that exhibits high gain and efficiency performance at the terahertz (THz) band and has a wide operational bandwidth. The proposed OCA is implemented on stacked silicon layers and consists of an open circuit meandering line. It is shown that by…

Synthesis of Cyano-Benzylidene Xanthene Synthons Using a Diprotic Brønsted Acid Catalyst, and Their Application as Efficient Inhibitors of Aluminum Corrosion in Alkaline Solutions

Mohammed Amin, Gaber Mersal, Morad El-Hendawy, Abdallah Shaltout, Ali Badawi, Johan Boman, Adil Gobouri, Murat Saracoglu, Fatma Kandemirli, Rabah Boukherroub, Jacek Ryl, Mohamed Khalifa

Novel cyano-benzylidene xanthene derivatives were synthesized using one-pot and condensation reactions. A diprotic Brønsted acid (i.e., oxalic acid) was used as an effective catalyst for the promotion of the synthesis process of the new starting xanthene–aldehyde compound. Different xanthene…

Combined surface x-ray diffraction and density functional theory study of the germanene/Al(111)-(7×7) R19.1° structure

K. Zhang, M.C. Hanf, D. Sciacca, Romain Bernard, Yves Borensztein, A. Resta, Yves Garreau, A. Vlad, A. Coati, Isabelle Lefebvre, M. Derivaz, C. Pirri, P. Sonnet, R. Stephan, G. Prévot

Several studies have reported the possible growth of germanene on various metal surfaces. However, the exact structure of the layers formed upon evaporation at or above room temperature remains controversial. In particular, the layers obtained after Ge deposition on Al(111) have been either…

Sub-nanosecond pulse technology applied to millimetre wave systems for TDoA-based geolocalization

Christophe Loyez, Michael Bocquet, Nathalie Rolland, Kamel Haddadi

This study deals with a geolocation system that uses sub-nanosecond pulsed radio signals. Based on Time Difference of Arrival (TDoA), it allows the localization of 60-GHz transmitters in an indoor environment with an accuracy compatible with the requirements of the next generation of communicating…

In-plane InGaAs/Ga(As)Sb nanowire based tunnel junctions grown by selective area molecular beam epitaxy

Alexandre Bucamp, Christophe Coinon, Sylvie Lepilliet, David Troadec, Gilles Patriarche, M Diallo, Vanessa Avramovic, Kamel Haddadi, X. Wallart, L. Desplanque

In-plane InGaAs/Ga(As)Sb heterojunction tunnel diodes are fabricated by selective area molecular beam epitaxy with two different architectures: either radial InGaAs core/Ga(As)Sb shell nanowires or axial InGaAs/GaSb heterojunctions. In the former case, we unveil the impact of strain relaxation and…

Contactless Rheology of Soft Gels over a Broad Frequency Range

Zaicheng Zhang, Muhammad Arshad, Vincent Bertin, Samir Almohamad, Elie Raphaël, Thomas Salez, Abdelhamid Maali

We report contactless measurements of the viscoelastic rheological properties of soft gels. The experiments are performed using a colloidal-probe Atomic Force Microscope (AFM) in a liquid environment and in dynamic mode. The mechanical response is measured as a function of the liquid gap thickness…
