La connaissance de la surface équivalente radar (SER) à moindre coût est utile dans le contexte de l’extension des techniques radar pour les applications civiles et militaires. Cette thèse est consacrée à l’introduction de nouvelles méthodes de mesure de la SER d’une cible. Ces nouvelles méthodes se basent sur les propriétés statistiques d’une cham...
Magnetic Resonance Imaging (MRI) is a non-invasive technique commonly used in clinical practice, based on the principle of nuclear magnetic resonance (NMR). Increasing the static magnetic field (denoted as B₀) is associated with a higher signal-to-noise ratio. To fully capitalize on the intrinsic gain provided by the increase in B₀, radio-frequency...
Les nanocristaux colloïdaux sont des nanoparticules dont la croissance se fait en solution. Lorsque la taille de ceux-ci est suffisamment faible, des effets de confinement quantique apparaissent et leurs propriétés optiques deviennent ajustables avec leur taille. Ces nanocristaux sont en particulier utilisés pour leur luminescence dans le visible m...
The response of open optical resonators to excitation can be expressed as a superposition of their intrinsic resonances, their quasinormal modes (QNM), which are loaded by the driving field and decay exponentially in time due to power leakage or absorption. Quasinormal modes are the eigensolutions of the time-harmonic Maxwell’s equations et complex...
The long-range propagation of electromagnetic waves is a major issue in telecommunication, navigation, and surveillance. The objective of this Ph.D. thesis is to develop fast and accurate modeling methods for the tropospheric propagation in 2D and 3D. In this work, two main contributions towards this objective are achieved. Firstly, self-consistent...
