1. Cylindrical Waveguide Slot Antenna Analysis
Sammanfattning : Waveguide slot antennas with longitudinal and transverse slots are analyzed using a rigorous method. The antennas are divided into regions, which are analyzed separately and matched by a moment method procedure. At the apertures between the regions, the electric fields are expanded in trigonometric basis functions. LÄS MER
2. Computation of EMC Properties of Slots and Printed Circuit Boards
Sammanfattning : This thesis deals with the numerical solution of electromagnetic compatibility (EMC) problems for electronic systems, such as radiated emission, susceptibility and crosstalk on printed circuit boards and transmission through slots. The analysis of printed circuit boards is done by using an electric field integral equation (EFIE) expressed in the frequency domain, which is solved by using the method of moments. LÄS MER
3. Theoretical Investigations of the Role of Ion-Ion Correlations and Ion-Specific Interactions in Electric Double Layers
Sammanfattning : Electric double layers are ubiquitous, arising in some form in almost every situation involving an interface with an aqueous electrolyte solution. In order to gain insight into the behavior of electrolytes and electric double layers, simple models of bulk and inhomogeneous electrolyte solutions are considered in this thesis. LÄS MER
4. Radome Diagnostics: utilizing Source Reconstruction based on Surface Integral Representations
Sammanfattning : In this thesis, an inverse source reconstruction method with great potential in radome diagnostics is presented. A radome is a cover that encloses an antenna in order to protect it from environmental influences. LÄS MER
5. Analysis of Planar and Circular Cylindrical Multilayer Structures with Application to Soft and Hard Surfaces
Sammanfattning : This thesis deals with the analysis of planar and circular cylindrical multilayer structures, such as strip-loaded dielectric layers, corrugated surfaces and microstrip antennas. In particular, we study corrugations and strip-loaded grounded dielectric slabs when they are used to realize soft and hard surfaces. LÄS MER
