Design and modeling of a specific microwave applicator for the treatment of snoring

Pierre-Yves Cresson, C. Ricard, Nicolas Bernardin, Luc Dubois, Joseph Pribetich

One of the main objectives of using microwaves in medical applications is to make use of the therapeutic effects resulting from the interaction between electromagnetic waves and biological tissues in order to obtain a local heating. For this purpose, a large number of devices have been designed and…

Humidity effects on the electrical properties of hexagonal boron nitride thin films

Ali Soltani, P. Thevenin, H. Bakhtiar, A. Bath

Thin films of hexagonal boron nitride (h-BN) were grown by a plasma enhanced chemical vapour deposition (PECVD) technique. The quality of the films was assessed by infrared spectroscopy, microRaman spectroscopy as a function of annealing temperature and by X-ray photoelectron spectroscopy. The…

Exons, introns and DNA thermodynamics

Enrico Carlon, Mehdi Lejard Malki, Ralf Blossey

The genes of eukaryotes are characterized by protein coding fragments, the exons, interrupted by introns, i.e. stretches of DNA which do not carry any useful information for the protein synthesis. We have analyzed the melting behavior of randomly selected human cDNA sequences obtained from the…

Electrical damage induced by reactive ion-beam etching of lead-zirconate-titanate thin films

Caroline Soyer, Eric Cattan, Denis Remiens

Ion-beam etching of sputtered Pb(Zrx,Ti1-x)O3 (PZT) thin films with x equal to 0.54 grown on Pt/TiOx/SiO2/Si substrates has been performed using pure Ar gas and a varying CHF3/Ar gas mixing ratio. The etch rate dependence on the process parameters (gas composition, current density, and acceleration…

Photonic devices based on preferential etching

Bob Bellini, Jean-François Larchanché, Jean-Pierre Vilcot, Didier Decoster, Romeo Beccherelli, Antonio D’alessandro

We introduce a design concept of optical waveguides characterized by a practical and reproducible process based on preferential etching of crystalline silicon substrates. Low-loss waveguides, spot-size converters, and power dividers have been obtained with polymers. We have also aligned liquid…
