The module aims to provide skills on guiding structures, components and distributed-element circuits operating at radio and microwave frequencies. These topics are proposed starting from the theoretical bases and analyzing practical case studies in the field of electronic engineering.
This course aims at providing the basic competences about distributed-element circuits operating at radio and microwave frequencies.
Lectures and laboratory experiences.
Students with valid certifications for Specific Learning Disorders (SLDs), disabilities or other educational needs are invited to contact the teacher and the School's contact person for disability at the beginning of teaching to agree on possible teaching arrangements that, while respecting the teaching objectives, take into account individual learning patterns. Contacts of the School's disability contact person can be found at the following link Comitato di Ateneo per l’inclusione delle studentesse e degli studenti con disabilità o con DSA | UniGe | Università di Genova" (https://unige.it/en/commissioni/comitatoperlinclusionedeglistudenticondisabilita)

The timetable for this course is available here: EasyAcademy
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).
Students with valid certifications for Specific Learning Disorders (SLDs), disabilities, or other educational needs are invited to contact the teacher and the DITEN contact person for disability to agree on the possible use of specific modalities and supports that will be determined on a case-by-case basis, according to the University regulation for the inclusion and right to study of students with disabilities or specific learning disorders.
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. The knowledge of these topics is assessed during the oral exam, when the student is asked to discuss them in detail.
Ask the professor for other information not included in this description of the teaching unit.
