Reliability studies of electrostatically actuated MEMS
This thesis summarizes the work concerning reliability testing of electrostatic capacitive- and ohmic-type RF MEMS switches developed by the CEA-Leti. In the first... -
Miniaturized and reconfigurable antennas using dielectric and ferroelectric o...
Given the desire to integrate a large number of new services in latest generation of hand held devices and in order to meet their dimensional constraints, new concepts... -
Effect of Laser field on Collision Frequencies and Absorption during Ultra-Sh...
Laser-induced electronic excitation, absorption and relaxation are the key issues in ultra-short laser interactions with dielectric materials. To numerically analyze... -

Metal-to-Dielectric transition induced by annealing of oriented titanium thin...
Titanium thin films were deposited by DC magnetron sputtering. The glancing angle deposition (GLAD) method was implemented to prepare two series of titanium films:... -
Simplified industrial nanocomposites: structural analysis and mechanical prop...
In this thesis, we study nanocomposite materials made of rubber (styrene-butadien copolymer "SBR") reinforced by highly dispersible silica nanofillers. In order to... -
