2. Dielectric Relaxation in Dielectric Mixtures
Abstract : In this thesis dielectric properties of both ideal composite structures and polymeric composite materials were investigated. Numerical calculations were performed to simulate frequency response of interfacial polarization using the finite element method in two dimensions. READ MORE

3. Reliable hp finite element computations of scattering resonances in nano optics
Abstract : Eigenfrequencies are commonly studied in wave propagation problems, as they are important in the analysis of closed cavities such as a microwave oven. For open systems, energy leaks into infinity and therefore scattering resonances are used instead of eigenfrequencies. READ MORE

4. Inverse and optimization problems in electromagnetics -- a finite-element method perspective
Abstract : In this thesis, a selection of inverse and optimization problems are studied where the finite element method (FEM) serves as a comprehensive tool to solve electromagnetic field problems that lack an analytic solution. The inverse problems are typically formulated in terms of an optimization problem where the misfit between a measurement and the corresponding result of a computational model is minimized. READ MORE

5. Effect of Dielectric and Magnetic Material Characteristics on Frequency Response of Power Transformers
Abstract : Frequency response analysis (FRA) technique has become increasingly popular for the assessment of mechanicalintegrity in power transformers. This method is based on the fact that the shape of the frequency response at higher frequencies is uniquely determined by the geometrical construction of the transformer. READ MORE
