L. Dobrzynski, Housni Al Wahsh, Abdellatif Akjouj, El Houssaine El Boudouti, Cécile Ghouila-Houri, Abdelkrim Talbi, Gaëtan Lévêque, Bahram Djafari-Rouhani

A closed loop can be obtained by linear superposition of the two free ends of an open loop. Its main property is the double degeneracy of its states. The analytical expressions of its eigenvalues, eigenfunctions, and response function are presented. The case of two simultaneous identical measures…

Heuristically accelerated reinforcement learning for channel assignment in wireless sensor networks

Mohamed Sahraoui, Azeddine Bilami, Abdelmalik Taleb-Ahmed

In wireless sensor networks (WSNs), multi-channel communication represents an attractive field due to its advantage in improving throughput and delivery rate. However, the major challenge that faces WSNs is the energy constraint. To overcome the channel assignment problem in an energy-efficient way…

H-Band Substrate-Integrated Discrete-Lens Antenna for High Data Rate Communication Systems

Kossaila Medrar, Loïc Marnat, Laurent Dussopt, Cybelle Belem-Gonçalves, Guillaume Ducournau, Cyril Luxey, Frédéric Gianesello

A substrate-integrated discrete-lens antenna manufactured in standard printed-circuit-board (PCB) technology is demonstrated in H-band (225-325 GHz). The arrays composed of phase-shifting unit cells and a waveguide-fed planar focal source are designed on a single PCB stack with five metal layers…

Oxygen vacancy engineering of TaO$_x$-based resistive memories by Zr doping for improved variability and synaptic behavior

João Palhares, Yann Beilliard, F. Alibart, Everton Bonturim, Daniel de Florio, Fabio Fonseca, Dominique Drouin, Andre Ferlauto

Resistive switching (RS) devices are promising forms of non-volatile memory. However, one of the biggest challenges for RS memory applications is the device-to-device (D2D) variability, which is related to the intrinsic stochastic formation and configuration of oxygen vacancy (V$_O$) conductive…

Piezoresistance in defect-engineered silicon

Heng Li, Abel Thayil, Chris Lew, Marcel Filoche, Brett Johnson, Jeff Mccallum, S. Arscott, Alistair C. H. Rowe

The steady-state, space-charge-limited piezoresistance (PZR) of defect-engineered, silicon-on-insulator device layers containing silicon divacancy defects changes sign as a function of applied bias. Above a punch-through voltage (Vt) corresponding to the onset of a space-charge-limited hole current…

A new equivalent circuit scheme for grounded back-to-back GCPW-MS-GCPW transitions fabricated on a thin low-k substrate

Pierre-Vincent Dugué, Mohammed El Gibari, Mathieu Halbwax, Stephane Ginestar, Vanessa Avramovic, Jean-Pierre Vilcot, Hong Wu Li

We hereby present a new equivalent circuit model including both lumped and distributed elements for GCPW-MS transitions (GCPW for Grounded CoplanarWaveguide and MS for Microstrip). In order to validate the modelling results, such transitions have been fabricated on a 20 μm-thick BCB (…
