Multiport Reflectometer Based on Subtractive Mixing

Abdelhatif El Fellahi, Kamel Haddadi, David Glay, Tuami Lasri

A compact multiport reflectometer using a new subtractive mixing scheme for the determination of reflection coefficients in the frequency range of 1-10 GHz is proposed. Compared with classical multiport reflectometers, the architecture proposed reduces the design complexity. Comparison between...

Optimization of a tunable piezoelectric resonator using phononic crystals with periodic electrical boundary conditions

Marie-Fraise Ponge, Bertrand Dubus, Christian Granger, Jerome O. Vasseur, Mai Pham Thi, Anne-Christine Hladky

Piezoelectric phononic crystals with periodic short-circuit conditions exhibit Bragg band gaps. They are used to design a Fabry-Perot cavity. The design of the device enables a modification of cavity length by a spatial shift of electrical boundary conditions. The resonator is thus tunable and a...

Modeling and de-embedding the interferometric scanning microwave microscopy by means of dopant profile calibration

L. Michalas, Fei Wang, Charlene Brillard, Nicolas Chevalier, Jean-Michel Hartmann, Romolo Marcelli, Didier Theron

This paper presents the full modeling and a methodology for de-embedding the interferometric scanning microwave microscopy measurements by means of dopant profile calibration. A Si calibration sample with different boron-doping level areas is used to that end. The analysis of the experimentally...

Spectrum sensing applied to IR-UWB system based on M-OAM

Lamyae Maatougui, H. Ouahmane, A. Hajjaji, Khadija Hamidoun, Atika Rivenq, Yassin El Hillali

Intelligent transport system (ITS) exploits new communication and information technologies to make existing infrastructures more effective and more reliable, it resets on functions associated with the intelligence. The use of the ultra-wideband (UWB) appears as a very suitable technology for this...

Optically-pumped continuous-wave terahertz sources

Philipp Latzel, Fabio Pavanello, Emilien Peytavit, Mohammed Zaknoune, Guillaume Ducournau, X. Wallart, Jean-Francois Lampin

Recently we have improved the efficiency and the output power of our optically pumped continuous-wave THz sources. These sources are based on the beating of two laser lines in a wide bandwidth photodetector. Its intrinsic nonlinear behaviour is used to produce a beatnote at the frequency difference...
