Course description

This is a course that belongs to the field of applied electromagnetics (ING-INF/02 – Electromagnetic fields). The course aims at providing advanced knowledge of electromagnetic compatibility. Biomedical implications and the 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.

Judgement skills:
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.

Communication skills:
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.

Learning skills:
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 achieve a deeper knowledge of the biomedical electromagnetic compatibility and its regulations, being able to follow technical courses and seminars on the topic.
