On the Fréchet derivative in elastic obstacle scattering
In this paper, we investigate the existence and characterizations of the Fréchet derivative of solutions to time-harmonic elastic scattering problems with respect to... -
Study and realization of an UWB microwave radar based on phase conjugation
This thesis deals with non-destructive electromagnetic imaging. Its originality lies, primarily, in a marked experimental approach, which has led to the realization of... -
On the use of the Reciprocity-Gap functional in inverse scattering from plana...
We consider the inverse problem of determining the shape and location of planar screens inside a 3D body through acoustic or electromagnetic imaging. In order to... -
Spectral Methods for Direct and Inverse Scattering from Periodic Structures
The main topic of the thesis are inverse scattering problems of electromagnetic waves from periodic structures. We study first the direct problem and its numerical... -
Advanced Interacting Sequential Monte Carlo Sampling for Inverse Scattering
The following electromagnetism (EM) inverse problem is addressed. It consists in estimating local radioelectric properties of materials recovering an object from... -

In this paper, we consider inverse scattering and inverse boundary value problems at sufficiently large and fixed energy for the multidimensional relativistic Newton... -
Nonlinear estimation and control: application to some quantum and classical s...
This manuscript is divided into two main parts, associated with two quite different types of applications. In the first part, which includes the first two chapters, I... -
