1. Wave Splitting in Direct and Inverse Scattering Problems
Sammanfattning : The focus of this thesis is on the use of wave splitting in electromagnetic direct and inverse scattering problems. Wave splitting offers a decomposition of wave fields into appropriate input and output wave constituents. LÄS MER
2. Direct imaging of Stimulated Raman scattering : 3D spatial control and spatial generation
Sammanfattning : Stimulated Raman scattering (SRS) is a powerful imaging technique that has become popular during the last decades for its ability to image species specific in a sample with high accuracy. The purpose of this thesis is twofold. Firstly, to demonstrate 3D spatial control of where in the sample SRS is generated. LÄS MER
3. Colloidal interactions obtained from total internal reflection microscopy measurements and scattering data
Sammanfattning : The scattering of radiation can be used to extract information about the interactions between colloidal (10^{-7}-10^{-3} cm radius) particles suspended in liquids. As colloidal interactions incorporate entropic effects they are weak and while system specific they are governed by a number of general mechanisms. LÄS MER
4. Computational Methods and Measurements for Direct and Inverse Scattering of Microwaves
Sammanfattning : Electromagnetic waves are widely used in society today for a multitude of applications. Design of electromagnetic devices and applications requires accurate methods for evaluating performance, which often means modern computational methods. LÄS MER
5. Enhancing Direct Searches for Dark Matter : Spatial-Temporal Modeling and Explicit Likelihoods
Sammanfattning : Astronomical and cosmological observations on different scales point to the existence of dark matter. In the current cosmological paradigm this dark matter accounts for about 26% of the energy-density of the universe, yet has not been directly observed. LÄS MER
