Cancellation Technique for CW Ground Penetrating Radar Applications

S. Nounouh, Kamel Haddadi, T. Lasri

An adjustable canceller based on microwave interferometry is proposed for ground penetrating radar applications. This canceller, built up with a power divider and an impedance tuner, is integrated in a monostatic continuous wave (CW) radar in order to improve its measurement sensitivity. A set of…

Forward V-band Vector Network Analyzer Based on a Modified Six-port Technique

Kamel Haddadi, Tuami Lasri

A V-band forward network analyzer based on a modified six-port technique is proposed for the measurement of complex reflection (S-11) and transmission (S-21) coefficients. The millimeter-wave part of the system is implemented on a thin alumina ceramic substrate. The measurement performance is…

Room-Temperature, Zero-Bias Plasmonic THz Detection by Asymmetric Dual-Grating-Gate HEMT

Takayuki Watanabe, Tetsuya Kawasaki, Akira Satou, Stéphane Boubanga-Tombet, Tetsuya Suemitsu, Guillaume Ducournau, Dominique Coquillat, Wojciech Knap, Hiroaki Minamide, Hiromasa Ito, Viacheslav Popov, Yahya Moubarak Meziani, Taiichi Otsuji

We study theoretically and experimentally the plasmonic THz detection by the asymmetric dual-grating-gate HEMT at room temperature without source-to-drain bias. We derive the analytical expressions of photocurrents due to the plasmonic drag and ratchet effects, and we discuss about their frequency…

Modeling of ZigBee (IEEE 802.15.4) channel in rail environment for Intelligent Transport

Ulrich Biaou, Laïd Sadoudi, Michael Bocquet, Atika Rivenq

To deploy Wireless Sensor Networks (WSNs) in the railway transport, knowledge of signal propagation in this environment is required for the safety and the reliability of whole system. This calls to two domains of research. Firstly, the study of the propagation characteristics is necessary to…

A Unified Explanation of gm /ID -Based Noise Analysis

Jack Ou, Pietro Maris Ferreira

We present an unified explanation of the transconductance-to-drain current (gm/ID)-based noise analysis in this paper. We show that both thermal noise coefficient (γ) and device noise corner frequency (fco) are dependent on the gm/ID of a transistor. We derive expressions to demonstrate the…

When capacitive transduction meets the thermomechanical limit: Towards femto-newton force sensors at very high frequency

S. Houmadi, Bernard Legrand, J.P. Salvetat, B. Walter, E. Mairiaux, J.P. Aime, D. Ducatteau, P. Merzeau, L. Buisson, J. Elezgaray, Didier Theron, Marc Faucher

We show that the capacitive transduction of a MEMS device using a setup based on a microwave detection scheme achieves the measurement of the thermomechanical noise spectrum of a high-frequency (>10 MHz) high-stiffness (>10 5 N/m) resonator, reaching the outstanding displacement resolution of…

0.69 THz room temperature heterodyne detection using GaN nanodiodes

Carlos Daher, Jeremie Torres, Ignacio Iñiguez-De-La-Torre, Philippe Nouvel, Luca Varani, Paul Sangaré, Guillaume Ducournau, Christophe Gaquière, Javier Mateos, And Tomás González

GaN-based asymmetric nanodiodes have been used as heterodyne detectors up to 0.69 THz in free-space configuration where Intermediate Frequency bandwidth has been measured up 13 GHz. Monte Carlo simulations, used to estimate nano-device intrinsic conversion losses of 27 dB have confirmed these…
