This is a course that belongs to the field of applied electromagnetic (ING-INF/02 – Electromagnetic fields). The course aims at providing advanced knowledge of electromagnetic compatibility. The planning constraints imposed by regulations will be particularly addressed.
Knowledge and understanding:
The student is expected to achieve an advanced knowledge key mechanisms that lie at the basis of electromagnetic compatibility. The student is expected to know and to understand the main characteristics and analysis/solution of electromagnetic compatibility problems.
Applying knowledge and understanding:
The student is expected to achieve an advanced knowledge in terms of modeling, analysis and solution with respect to the regulations that rule the different problems of electromagnetic compatibility.
Autonomy of judgement:
The student is expected to identify the challenges that characterize electronic devices or real scenarios in terms of electromagnetic compatibility, in order to provide the best planning and technological solutions within the framework of regulations.
The student is expected to explain the modeling, analysis and solution background that lies at the basis of electromagnetic compatibility using a clear and effective technical language suitable even for non-expert interviewer.
The student is expected to achieve a self-understanding stage to update his knowledge using different sources, e.g. books and scientific papers, and to follow technical courses and seminars on the topic.
Although there are no formal prerequisites, the basic knowledge of main topics related to the SSD ING/INF-02 is recommended:

The examination aims at verifying the previously stated educational targets. The examination consists of an oral exam, discussed even in English language, that aims at evaluating the student’s ability to link and analyze the topics studied during the course and to address typical practical problems of electromagnetic compatibility.
