1. On Performance of Digital Radio Receiver in Non-Gaussian Interference
Abstract : Interference from electrical equipment can degrade a co-located digital radio receiver severely. To avoid this performance degradation it is necessary to have estimation methods to predict the influence from an interference environment on a radio receiver in advance. READ MORE

2. Computation of EMC Properties of Slots and Printed Circuit Boards
Abstract : 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. READ MORE

4. Conducted and Radiated Electromagnetic Interference in Modern Electrified Railways with Emphasis on Pantograph Arcing
Abstract : Arcing from the pantograph, a commonly observed phenomenon, is knownto be a major source of wideband electromagnetic emission which is more pronounced during the winter. Experience within the railway industry has shown that this source of EMI and its characteristics need to be understood thoroughly for solving the associated EMI issues in the desired fashion.

5. High-frequency noise in power grids, neutral and protective earth
Abstract : This licentiate thesis deals with the high-frequency distortion, 1 kHz and higher, introduced into the power grid by the numbers of power converters in use today. These devices can be a source of electromagnetic interference and equipment damage despite the fact that the equipment complies product-standards testing. READ MORE
