2nd Cycle Studies - Mestrado
Electromagnetism, Waves and Propagation, Electric Circuits
There are three types of classes: theoretical (lectures); theoretical-practical classes with problem solving and some basic experiments; seminar classes for the students to present and defend their assessment works.
To understand important concepts of Electromagnetic Compatibility which are fundamental for the design of electrical systems and devices, from the point of view of the equivalent electric circuit, in order to minimize electromagnetic interference. These concepts will be applied to a frequency range covering conduction and radiation, according the applicable standards.
1. Introduction to Electromagnetic Compatibility (EMC). Applicable standards.
2. Transmission lines and signal integrity. Reflections and refractions. Load match.
3. Conducted emissions, radiated emissions and susceptibility. Measurements.
4. Crosstalk. Inductive model and capacitive model. Reduction of crosstalk.
5. Non-ideal behaviour of passive components: conductors, resistances, inductances and capacities at low and high frequencies.
6. Noise reduction. Filters and common-mode inductances (chokes). Mechanical switches and electrical arc suppression.
7. Antennas. Dipoles and monopoles. Antennas characterization (directivity, gain, affective aperture, antenna factor).
8. Shielding principles and efficiency.
9. Earthing and grounding.
