1. EMC barriers : measurement methodologies and model verification
Sammanfattning : The subject of Electromagnetic Compatibility (EMC) is introduced. A short overview of the regulatory EMC requirements in Europe and in the United States is presented. An explanation is given why it is important for people in the electronics business to understand the need for EMC regulations. LÄS MER
2. EMC in railway systems : measurements, modeling and analysis
Sammanfattning : The subject of this study and resulting thesis was to investigate the electromagnetic compatibility (EMC) problems in the multi-electrical signaling circuitry along a railway track. These signaling systems have been expanding over time from buried multi-wired electrical copper cables to optical fiber cables, sometimes located parallel to the contact line in the catenaries.

4. 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
5. Mitigation of Power-Frequency Magnetic Fields With Applications to Substations and Other Parts of the Electric Network
Sammanfattning : In recent times, electromagnetic emissions from various electrical components have induced more than one debate whether they represent a harmful influence to our health. In addition, interferences caused by power frequency magnetic fields (PFMFs) on electron beam based electronic equipment (e.g. LÄS MER
