The first objective of this work is devoted to the study of strategies for the synthesis of azo-compounds and their derivatives, among other things, highlighting "the properties of azo dyes" known for their importance ...

Plasma polymerization of hexamethyldisiloxane (PPHMDSO) was used to deposit SiOxCyHz thin films on silicon and polyimide substrates, using low-frequency plasma and microwave plasma discharge at low pressure. The effects ...

The whole of this work is a characterization of the micro band antennas with and without excitation by the technique of the spectral domain. The solution of a single microstrip antenna is applied to an array of antennas. ...

"It has been observed that many physical systems are well characterized by linear fractional order models. Hence, their identification is attracting more and more interest of the scientific community. However, they pose ...

The continuous down-scaling of MOS transistors dimensions over the last years allowed a significant revolution in the semiconductor industry. However, in order to maintain this trend, shrinking of conventional n MOS ...

"This work proposes a contribution to studying, designing of the non planar antennas having a wide band for wireless communications. The first part is concerned to study planar antennas such as microstrip antenna (MSA) ...

The work of this thesis focuses on the design, modeling and realization of capacitive pressure sensors using the combination of two techniques PCB-MEMS. We started by describing the various manufacturing processes of ...

The ability to develop innovative photonic devices enabling the controlling of the flow of light at the nanoscale, has motivated a growing interest. In particular, planar photonic crystal cavities (PhCs) based struc tures ...
