Study of HF behaviour of railway power substation in reduced scale

H. Ouaddi, S. Baranowski, G. Nottet, B. Demoulin, L. Koné

The study presented in this paper is a first step of an EMC (Electromagnetic Compatibility) analysis of the behaviour of a railway power substation at high frequency. Before on site intensive experimentation, the approach is performed with a reduced scale model. The mock-up of the substation is...

Substrate integrated waveguide (SIW) inductive window band-pass filter based on post-wall irises

K. Nouri, Kamel Haddadi, O. Benzaïm, T. Lasri, M. Feham

In this article, we demonstrate a new inductive-window 5.245-GHz-band-pass filter based on post-wall irises by standard PcB process on Epoxy FR4 substrate. A new and easy to build microstrip-to-waveguide transition that consists of three tapers is also designed to connect the filter to standard...

Star-drops formed by periodic excitation and on an air cushion - A short review

Philippe Brunet, Jacco H Snoeijer

When simply put on a solid, a liquid drop usually adopts the shape of a spherical cap or a puddle depending on its volume and on the wetting conditions. However, when the drop is subjected to a periodic field, a parametric excitation can induce a transition of shape and can break the drop’s initial...

Deep structural analysis of novel BGaN material layers grown by MOVPE

S. Gautier, G. Patriarche, T. Moudakir, M. Abid, G. Orsal, K. Pantzas, David Troadec, A. Soltani, L. Largeau, O. Mauguin, A. Ougazzaden

BGaN ternary alloys with 0.7% and 1.7% boron grown on GaN/sapphire template substrates by metalorganic vapour phase epitaxy (MOVPE) have been investigated through HAADF-STEM. At low boron content, 0.7%, no compositional fluctuations were observed with XRD or STEM measurements. Photoluminescence at...

Structural and optical properties of nanodots, nanowires, and multi-quantum wells of III-nitride grown by MOVPE nano-selective area growth

W.H. Goh, G. Patriarche, P.L. Bonanno, S. Gautier, T. Moudakir, M. Abid, G. Orsal, A.A. Sirenko, Z.-H. Cai, A. Martinez, A. Ramdane, L. Le Gratiet, David Troadec, A. Soltani, A. Ougazzaden

Nanodots, nanowires, and semi-polar quantum well structures of GaN-based material have been grown by nano-selective area growth (NSAG). The growth evolution of the nanostructure has been studied. Cross-sectional transmission electron microscopy (TEM) shows that the nanostructures are free of...

Above 600 mS/mm transconductance with 2.3 A/mm drain current density AlN/GaN high electron mobility transistors grown on silicon

F Medjdoub, Malek Zegaoui, Nicolas Waldhoff, B. Grimbert, N. Rolland, Paul-Alain Rolland

AlN/GaN high-electron-mobility transistors (HEMTs) capped with an in-situ grown SiN have been successfully developed on 100mm Si substrates. A unique combination of maximum output current density exceeding 2A/mm and a record extrinsic transconductance above 600 mS/mm has been reached, which is well...
