Experimental investigation of the characteristics of the electromagnetic reverberation in the UWB bands

Aliou Bamba, Wout Joseph, Emmeric Tanghe, Luc Martens, Davy Gaillot, M. Lienard, Jose-Maria Molina-Garcia-Pardo, Maria-Teresa Martinez-Ingles

The electromagnetic reverberation time characteristics are investigated at UltraWide Band (UWB) frequencies, i.e., from 2 to 10 GHz. The reverberation time is bandwidth independent and decreases as the frequency increases. Besides, the reverberation ratio - the contribution of the diffuse fields in…

High performance TiN gate contact on AlGaN/GaN transistor using a mechanically strain induced P-doping

Ali Soltani, Michel Rousseau, Jean-Claude Gerbedoen, Maghnia Mattalah, P.L. Bonanno, A. Telia, Nour Eddine Bourzgui, Gilles Patriarche, A. Ougazzaden, A. Ben Moussa

High performance titanium nitride sub-100 nm rectifying contact, deposited by sputtering on AlGaN/GaN high electron mobility transistors, shows a reverse leakage current as low as 38 pA/mm at VGS = -40 V and a Schottky barrier height of 0.95 eV. Based on structural characterization and 3D…

Limitations of the impulse response of GaAs MSM photoswitch

Sabah Benzeghda, Farida Hobar, Didier Decoster, Jean-Francois Lampin

As symmetrical data characteristics I (V) of the Metal-Semiconductor-Metal (MSM) photodetector, we wondered how this device can be used as a photoswitch as well as the low temperature on GaAs photoconductive generally used for this purpose. The impulse response of interdigitated metal-semiconductor…

Microwave optical switches metal-semiconductor-metal Schottky based on GaAs

Sabah Benzeghda, Farida Hobar, Didier Decoster, Jean-Francois Lampin, A. Benzeghda

Interdigitated metal-semiconductor-metal (MSM) photodetectors have received considerable attention for applications in microwave optical phoswitches. The impulse response of interdigitated metal-semiconductor- metal photoswich fabricated on GaAs non-intentional doped (NID) absorbing layer is…

GaN high electron mobility transistors on silicon substrates with MBE/PVD AlN seed layers

Yvon Cordier, Éric Frayssinet, Magdalena Chmielowska, Maud Nemoz, Aimeric Courville, Philippe Vennéguès, P. de Mierry, Sebastien Chenot, Julien Camus, Keltouma Aït Aïssa, Quentin Simon, Laurent Le Brizoual, Mohamed Abdou Djouadi, N. Defrance, Marie Lesecq, Philippe Altuntas, Adrien Cutivet, Alain Agboton, Jean-Claude de Jaeger

In the present paper, we describe the development of new AlN seed layers obtained by combining molecular beam epitaxy and low temperature physical vapour deposition (magnetron sputtering). It is shown that it is possible to grow thick AlN seed layers with a good in-plane crystal ordering. GaN based…

Electrical method for crosstalk cancellation in transducer arrays

Abdelmajid Bybi, Christian Granger, Sébastien Grondel, Anne-Christine Hladky, Jamal Assaad

In this paper, we report a new and simple electrical method to cancel crosstalk in the acoustical arrays. This solution has several advantages compared with that proposed in a previous paper (Bybi et al 2013) [17] where adapted electrical voltages were applied to each neighboring element of the…

CW Radar for Monitoring Water-to-Cellular Concrete

Kamel Haddadi, Tuami Lasri

The physical deterioration of concrete structures is mainly caused by their moisture content. Consequently, methods dedicated to contactless, non-destructive and real-time monitoring of moisture content levels are required to control the deterioration of buildings. In this study, we propose an…

Determination of noise figure of differential circuits using correlation of output noise waves

Yogadissen Andee, J. Prouvée, F. Graux, Francois Danneville

The noise characterisation of differential circuits is considered. A new method for the determination of the differential mode noise power at the output of these circuits is presented. It is demonstrated that this differential noise power depends not only on the output noise powers but also on the…
