Based on theoretical fundamentals such as Maxwell equations, students will acquire insight into electromagnetic effects and ability to solve simple electromagnetic problems. Physical principles are applied to derive basics of circuit theory. Simple linear circuits, lumped as well as distributed, are described and analysed. Field theory application enables to understand basic circuit elements, such as resistors, capacitors, inductors, and transmission lines as well as important effects such as resonance and impedance matching. Exact quantitative description (analysis and/or design) of simple geometries helps to estimate fields and behaviour of more complex ones. Frequency domain and time domain formulations are combined to provide better insight. The course is completed by information on electromagnetic compatibility.
