Teaching methods
Lessons (75%);
classroom exercise(15%);
group experimental and CAD experiences in laboratory (5%);
seminars given by external experts (5%).
Assessment methods and criteria
The exam comprises a written test and an oral discussion.
The written test will present exercises to allow the student to apply knowledge and understanding of analysis and design tools on transmission lines, antennas and radiofrequency links.
The oral discussion is aimed to verify the student knowledge and understanding of basic electromagnetic guided and free space propagation as well as the working principles of transmission lines and antennas. The discussion will also include a presentation of lab experiences.
