Magneto-optical Effects in Transparent Media under Inhomogeneous Magnetization

The analysis of the Magneto-Optical (M. 0.) effects when the magnetization is inhomogeneous is separated in two cases : first, when no diffraction occurs inside the medium, the geometrical optics approximation is used to derive the phase of the optical fields and the ray paths. Second, with no negligible diffraction inside themedium, extensions of the previous theory are presented and applied t...

Optical Waves in Inhomogeneous Kerr Media Beyond Paraxial Approximation

This thesis deals with the propagation of optical waves in Kerr nonlinear media, with emphasis on optical beam propagation beyond the slowly varying envelope approximation (SVEA). The first topic in this thesis is the propagation of a continuous-wave in one-dimensional (1D) nonlinear grating structures. For this purpose we develop a numerical scheme based on a variational method. It directly im...

Optimal Control of Light Propagation Governed by Eikonal Equation within Inhomogeneous Media Using Computational Adjoint Approach

A mathematical model is presented in the present study to control‎ ‎the light propagation in an inhomogeneous media‎. ‎The method is ‎based on the identification of the optimal materials distribution‎ ‎in the media such that the trajectories of light rays follow the‎ ‎desired path‎. ‎The problem is formulated as a distributed parameter ‎identification problem and it is solved by a numerical met...

Branching diffusion in inhomogeneous media

We investigate the long-time evolution of branching diffusion processes (starting with a finite number of particles) in inhomogeneous media. The qualitative behavior of the processes depends on the intensity of the branching. In the super-critical regime, we describe the asymptotics of the number of particles in a given domain. In the sub-critical and critical regimes, we describe the distribut...

Lévy flights in inhomogeneous media.

We investigate the impact of external periodic potentials on superdiffusive random walks known as Lévy flights and show that even strongly superdiffusive transport is substantially affected by the external field. Unlike ordinary random walks, Lévy flights are surprisingly sensitive to the shape of the potential while their asymptotic behavior ceases to depend on the Lévy index mu. Our analysis ...
