Teaching methods
The teaching activities include lessons carried out in a lecture room, using mainly the blackboard (38 hours). In addition, practice (2 hours) and laboratory lessons (6 hours) are planned, with simulation activities carried out using the commercial software COMSOL Multiphysics for the analysis and the design of radio-frequency and microwave devices, such as antennas and waveguides.
Additional teaching material used during the lessons is weekly uploaded to the Elly web site. The registration to the course is necessary to download the slides.
Students who are not attending to the course should periodically check the teaching material and the information provided by the professor on the Elly web site.
Assessment methods and criteria
The learning assessment is made with an oral exam with questions on the topics developed during the lessons, with the aim to verify the student knowledge and understanding of basic electromagnetic propagation and working principles of microwave antennas. The oral exam is evaluated in the range 0/30. The mark of the oral exam is communicated to the student at the end of the oral test.
The online registration to the exam is mandatory and it is possible until three days before the exam date.
