The course in taught in English. The transport of information, in any electronic or photonic system, always occurs through the propagation of electromagnetic waves. These phenomena are completely described by Maxwell's equations, whose methodological study constitutes a fundamental point of all the curriculum in electronic and telecommunications engineering. In addition to the classic applications in the field of radio frequency, microwave, millimeter-wave and optic communications, the continuous growth of electronic technology makes it necessary to consider properly the electromagnetic phenomena in the design of almost all the electronic components and subsystems.

The course is organized as an alternance of frontal lectures, exercize sessions and experimental labs. Specifically 3 experimental labs are organized: 1. Measurements of scattering parameters for microstrip components with network analyser. (descriptive) 2. Measurements of scattering parameters with the slotted line. 3. Measurement of antenna radiation pattern.

Modalità di esame: Prova orale obbligatoria; Prova orale facoltativa; Prova scritta a risposta aperta o chiusa tramite PC con l'utilizzo della piattaforma di ateneo Exam integrata con strumenti di proctoring (Respondus);
The exam aims at assessing the specific knowledge of the topics listed in the course's official program and the ability to apply the theory and related design techniques to the solution of practical exercises. Following this approach, the exam consists of a first section with multiple choice questions about theory and a second section based on exercises in different formats (open questions, questions with a numerical answer, multiple choice questions). All these questions will be similar to the ones solved and discussed in class. The time for the exam will be 2 hours and it will be administered on a PC with the help of the platform Exam and of a proctoring software or as a PC-based test in laboratory in PoliTo with similar modalities. During the exam, texts and lecture notes (both in print or manuscript) are not allowed. The use of programmable calculators is forbidden. The maximum achievable mark of the written test is 27/30. In the case of a score of 18/30 or above, up to 3 additional points can be added, depending on the weekly delivery of the homework assignments and of the laboratory reports. If the final score of the exam is at least 27/30, an optional oral examination can be requested; the optional oral examination will be mainly aimed at analyzing the theoretical implications presented during the lectures and may include the critical discussion of the written test and of the laboratory activities. The oral examination can also be requested by the course instructor, in those cases he deem it necessary, to confirm the grade of the exam.
