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…

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…

Characterization of biodegradable and biosourced polylactic acid (PLA) substrate in a wide frequency range (0,5-26 GHz)

Ghizlane Boussatour, Pierre-Yves Cresson, Benoit Genestie, Nicolas Joly, T. Lasri

In this work, coplanar transmission lines were fabricated on a polylactic acid substrate. The transmission lines were then characterized in a broad microwave frequency band. From S-parameters measurements, the propagation constant was thus determined allowing the extraction of the complex effective…

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…
