An ultra broadband 0.5-18 GHz BPSK modulator

Paul Sangare, Christophe Loyez, Kevin Carpentier, Markus Mayer, Dirk Hartung, Francois Parickmiler, Nathalie Rolland

This paper presents an innovative topology of an ultra-broadband BPSK modulator. This novel architecture consists of a specific distributed amplifier and absorptive switches, providing amplitude flatness and low phase imbalance over the 0.5 - 18 GHz frequency bandwidth. Experimental results…

Approach-to-equilibrium molecular dynamics

Évelyne Martin, Pier Luca Palla, H. Zaoui, Fabrizio Cleri

Besides steady-state methods presented in Chapters 8 and 9, molecular dynamics simulations can also be used to simulate temperature transients, by means of approach-to-equilibrium molecular dynamics (AEMD) calculations. The interest for such methods is materialso the short MD simulation time…

High performance heterostructure low barrier diodes for sub-THz detection

Salman Nadar, Mohammed Zaknoune, X. Wallart, Christophe Coinon, Emilien Peytavit, Guillaume Ducournau, Florent Gamand, Maxime Thirault, Matthieu Werquin, Sylvain Jonniau, Nicolas Thouvenin, Christophe Gaquière, Nicolas Vellas, Jean-Francois Lampin

Heterostructure low barrier diodes (HLBD) based on lattice-matched AlGaInAs triangular barrier have been designed, fabricated, and characterized for zero-bias millimeter-wave and submillimeter-wave detection. Detectors with different barrier height and various active areas have been measured in…

A comprehensive study of magnetic exchanges in the layered oxychalcogenides Sr3Fe2O5Cu2Q2 (Q = S, Se)

Minfeng Lü, Olivier Mentre, Elijah E. Gordon, Myung-Hwan Whangbo, Alain Wattiaux, Mathieu Duttine, Nicolas Tiercelin, Houria Kabbour

The layered oxysulfide Sr3Fe2O5Cu2S2 was prepared, and its crystal structure and magnetic properties were characterized by synchrotron X-ray diffraction (XRD), powder neutron diffraction (PND), Mössbauer spectroscopy measurements and by density functional theory (DFT) calculations. In addition, the…

One-dimensional electromechanical equivalent circuit for piezoelectric array elements

Abdelmajid Bybi, Nadia El Atlas, Hilal Drissi, Mohammed Garoum, Anne-Christine Hladky

In this paper, we report a simple one - dimensional electromechanical method to model piezoelectric transducer array elements well known by slender bar elements. The method is inspired from the Mason's simplified model, which is tested in the case of a piezoelectric plate and extended to a…
