Coupling of two resonant modes for insect wing mimicking in a flexible-wing NAV and generate lift

Damien Faux, Eric Cattan, Sébastien Grondel, Olivier Thomas

This work is based on the original concept of coupling two resonant vibration modes to reproduce insect wing kinematics and generate lift. The key issue is designing the geometry and the elastic properties of the artificial wings to achieve quadrature coupling of the bending and twisting motions…

Combined scanning microwave and electron microscopy: a novel toolbox for hybrid nanoscale material analysis

Kamel Haddadi, O. C. Haenssler, K. Daffe, S. Eliet, Christophe Boyaval, Didier Theron, Gilles Dambrine

A novel toolbox for hybrid nanoscale material characterization is presented. The system consists of a nano-robotic, compact and modular near-field scanning microwave microscope (NSMM) integrated into a high resolution scanning electron microscope (SEM). The instrument developed can perform hybrid…

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…

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…

A D-Band Passive Receiver with 10 dB Noise Figure for In-situ Noise Characterization in BiCMOS 55 nm

Simon Bouvot, Thomas Quemerais, Joao Carlos Azevedo Goncalves, Sylvie Lepilliet, Guillaume Ducournau, Francois Danneville, Daniel Gloria

A millimeter-wave (mmW) frequency passive mixer for in-situ noise characterization in 110-170 GHz (Dband) is demonstrated using STMicroelectronics BiCMOS 55 nm technology. The circuit uses a gate-pumped MOS transistor with transmission lines filters, without any IF amplifier, allowing a direct…
