This thesis addresses the problem of diffusive transport in multilayer systems when the layers thickness is of the order of or even smaller than the mean free path. We...

In this work, ultraporous silica layers with very low refractive indices (1,1-1,2) and thicknesses about one micrometer are prepared and integrated to two systems of...

This work aims to develop, in thin film form, integrated structure based on tunable materials such as ferroelectrics and relaxor dielectrics for microwave devices....

This thesis presents an experimental and theoretical study of the acoustic phonon dynamics at the nanometric scale, by picosecond acoustic techniques and Raman...

An ellipsometer based on an elasto optic modulation of polarization has been developed. Compare to a rotating polarizer setup, the performances, in term of accuracy...

We have developed calculation code based on Mie theory, in order to predict the angular and spectral response of dielectric or metallic microspheres coated by...

Multilayer structures offer a large variety of behaviours with a great number of applications (multilayer elastomeric bearings used in earthquake engineering,...). The...

The deformation of plant cells during their growth can generate various anisotropic shapes. The envelop of the growing cells, also called primary wall of plants, is a...
