Subterahertz hypersound attenuation in silica glass studied via picosecond acoustics

Simon Ayrinhac, Marie Foret, Arnaud Devos, Benoit Ruffle, Eric Courtens, René Vacher

We report picosecond acoustic measurements in silica-glass films grown by wet thermal oxidation on a (111) silicon substrate. The longitudinal acoustic phonons are observed over the range from 150 to 300 GHz using an infrared pump and a second harmonic blue probe. The transducer is an aluminum thin...

Anisotropic excitonic effects in the energy loss function of hexagonal boron nitride

S. Galambosi, L. Wirtz, J.A. Soininen, J. Serrano, A. Marini, K. Watanabe, T. Taniguchi, S. Huotari, A. Rubio, K. Hamalainen

The anisotropy of the valence energy-loss function of hexagonal boron nitride (hBN) is shown to be largely enhanced by the highly inhomogeneous character of the excitonic states. The energy loss with momentum transfer parallel to the BN layers is dominated by strongly bound, quasi-two-dimensional...

Vortex state in thin films of multicomponent ferroelectrics

Laurent Baudry, Anaïs Sené, Igor A. Luk'Yanchuk, Laurent Lahoche

The distribution of polarization in thin film of multicomponent weak anisotropic ferroelectric under application of an axially symmetric electric field induced by circular electrodes is studied. We demonstrate that above a certain critical field the instability towards abrupt formation of...

Multiple description coding and scalable video coding combined with multiple input multiple output techniques : two strategies to enhance train to wayside video transmissions in tunnels

Imade Fatani, Yann Cocheril, Crépin Nsiala-Nzéza, Marion Berbineau, François-Xavier Coudoux, Marie Zwingelstein, Patrick Corlay

Video monitoring applications for underground rely on wireless train-to-wayside communication systems which require high data rate as well as high Quality of Service (QoS) level. In order to satisfy both constraints we propose a combined source and channel coding approach in the context of MIMO (...
