EXAMS

EXAM DESCRIPTION

At least three questions are asked during the oral exam: the first one is chosen by the student, the second is about theory, the last one is practical (an exercise, typically).

ASSESSMENT METHODS

After this course, students should demonstrate to know the fundamentals of guided electromagnetic propagation, as well as the operating principles of standard guiding systems and basic passive microwave components.
