    LESSONS START

    According to the academic calendar.

    Class schedule

    All class schedules are posted on the EasyAcademy portal.

    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 more practical (an exercise, typically).

    ASSESSMENT METHODS

    After this course, students should demonstrate to know the fundamentals of distributed-element circuits operating at radio and microwave frequencies, as well as the operating principles of standard guiding systems and basic passive radio-frequency/microwave components.
