Welcome to Electromagnetics
This course should provide the PhD candidates in the Wireless program the necessary background on the physical aspects of radiowave communication. The motivation follows the well-known fact that students in this program come from various backgrounds, often specialized in communication protocols and information theory, but lacking the necessary physical insight into electromagnetic fields, antennas and radiowave propagation. For the rest of the participants, this course should give a recapitulation of the previously acquired knowledge and extending it to meet the needs of their dissertation, as many of them will need to design an antenna and/or carry out electromagnetic simulations in their projects.
