F center in lithium fluoride revisited : comparison of solid-state physics and quantum-chemistry approaches

Ferenc Karsai, Paul Tiwald, Robert Laskowski, Fabien Tran, David Koller, Stefanie Gräfe, Joachim Burgdörfer, Ludger Wirtz, Peter Blaha

We revisit the theoretical description of the F color center in lithium fluoride employing advanced complementary ab initio techniques. We compare the results from periodic supercell calculations involving density-functional theory (DFT) and post-DFT techniques with those from the embedded-cluster...

Digital radio frequency signal generation towards ultimate transmitters

Antoine Frappé

This invited paper exposes our latest developments in the field of digital transmitters by focusing on digital and mixed-signal processing blocks, such as delta-sigma modulators, high-speed interpolation filters and digital-to-RF converters. The goal is to demonstrate that radio-frequency signal...

Polyaniline-carbon nanotubes composites - Based patch antenna

Z. Hamouda, J.-L. Wojkiewicz, A.A. Pud, B. Belaabed, S. Bergheul, T. Lasri

This paper presents the simulation and realization of a patch antenna made of composites based on Polyaniline (PANI) and carbon nanotubes (CNT). The antenna is designed to work at the frequency of 4.5 GHz; the dielectric substrates used is Rogers RT/duroid 5870 which has a dielectric permittivity...

Functionalized gold nanoparticles with electropolymerizable π-conjugated systems for a neuro-inspired memristive nanoparticle organic synapse-transistor

Ali Yassin, Maiténa Oçafrain, David Guérin, Stéphane Lenfant, Dominique Vuillaume, Philippe Blanchard, Jean Roncali

Nanoparticle Organic Memory Field-Effect Transistors (NOMFET) are molecule-based devices that exhibit the main behavior of a biological spiking synapse. This behavior is obtained by virtue of the combination of two properties of the NOMFET: the transconductance gain of the transistor and the memory...

Theoretical study of the basic mechanisms of DNA damage by therapeutic radiation beams

F. Manca, Stefano Giordano, Pier Luca Palla, Grégoire Perret, E. Lartigau, Dominique Collard, H. Fujita, Fabrizio Cleri

Cancer treatments by photon radiation beams in radiotherapy is currently grounded on a rather empirical understanding of the basic mechanisms of DNA damages. It is well assessed that radiation induces single-strand and double-strand breaks in DNA, being however the various mechanisms largely...

1-20 GHz k Omega-range BiCMOS 55 nm Reflectometer

Pietro M. Ferreira, Cora Donche, Kamel Haddadi, Tuami Lasri, Gilles Dambrine, Christophe Gaquière, Thomas Quemerais, Daniel Gloria

Scanning microwave microscope (SMM) combines the high spatial resolution with the high-sensitivity electric measurement capabilities of a vector network analyzer (VNA). SMM has been pointed out as very well suited for nanodevices characterization. In recent publications, SMM has demonstrated high...

Blind digital modulation identification for time-selective MIMO channels

Sofiane Kharbech, Iyad Dayoub, Marie Zwingelstein, Eric Pierre Simon, Kais Hassan

This paper addresses the problem of blind digital modulation identification in time-selective Multiple-Input Multiple-Output channels. Our objective is to recognize modulation schemes in highly-mobile communication environments, for military or high-speed railway applications, without signal...
