New millimeter wave generation scheme for MIMO-OFDM based Radio-over-Fiber system

M. El Yahyaoui, A. El Moussati, Ghaïs El Zein, Kamel Haddadi

This paper proposes a new scheme for the generation and transmission of a MIMO-OFDM signal over optical fiber using a single local oscillator (LO) at 15 GHz. This technique is based on subcarrier multiplexing and Optical Carrier Suppression (OCS) modulation using both Dual-Parallel Mach–Zehnder…

MEMS calorimetric transducers for flow separation detection and control

Cécile Ghouila-Houri, Abdelkrim Talbi, Romain Viard, Quentin Gallas, Eric Garnier, Alain Merlen, Philippe Pernod

Robust micro machined high temperature gradient calorimetric (HTGC) transducers were developed for flow separation control. Based on thermal principle, the transducers measure the mean and fluctuating bidirectional shear stress that is particularly useful for flow separation detection. More than a…
