Flat THz launcher antenna

Unai Beaskoetxea, Miguel Beruete, Mokhtar Zehar, Amit Agrawal, Shuchang Liu, Karine Blary, Abdallah Chahadih, Xiang-Lei Han, David Etayo, Miguel Navarro-Cia, Ajay Nahata, Tahsin Akalin, Mario Sorolla

1D and 2D leaky-wave corrugated antennas working at terahertz frequencies are numerically and experimentally studied. These structures allow temporal-pulse and beam shaping by engineering the leakage rate of the surface waves induced by the corrugations

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…

Transmission and attenuation of Lamb waves through a periodic array of rectangular slits in a plate

Rayisa P. Moiseyenko, Yan Pennec, Rémi Marchal, Bernard Bonello, Bahram Djafari-Rouhani

Acoustic wave transmission through sub-wavelength slits or holes, then on layers of periodically spaced cylinders and double fishnet structures, known as acoustic metamaterials has been studied in many works in relation with physical phenomena such as extraordinary resonant transmission, sound…

CIGSe absorber layers deposition by single target magnetron sputtering

R. Meunier, S. Fabert, M. Ricci, P.Y. Thoulon, Thomas Aviles, Jean-Pierre Vilcot, Alain Lafond, Michèle Carette, Pierre-Yves Jouan, Marie-Paule Besland

In the last decades, the deposition of CIGSe thin films by sputtering has seldom been investigated. Besides, the sputtering of a single quaternary CIGSe target would be a real advantage for industrial development. Indeed, sputtering technique exhibits a good compatibility with industrial up-scaling…

Impact of spacing between array elements on the performances of diversity schemes in tunnels

M. Lienard, Jose-Maria Molina-Garcia-Pardo, C. Sanchis-Borras, Pierre Degauque

To increase channel capacity in tunnels, MIMO seems to be a promising technique despite the low angular spread of the rays. Indeed, for transmitting frequencies on the order or larger than 1 GHz, the tunnel behaves as an oversized waveguide and the concept of spatial diversity can be replaced by…

In situ integrated tuner approach for load-pull measurement of Si/SiGe:C HBT at 200 GHz

Issam Hasnaoui, Alexandre Pottrain, Thomas Lacave, Pascal Chevalier, Daniel Gloria, Christophe Gaquière

Load impedance variations were obtained using an innovative integrated tuner at G-band. The 200 GHz load-pull measurements on a silicon-germanium (SiGe) heterojunction bipolar transistor (HBT) are presented. First, the linearity of the integrated tuner is checked. Then, the main load-pull…
