Subject fundamentals
This course provides the fundamental concepts of the electromagnetic compatibility (EMC) for the reliable integration of electrical and electronic systems employed by different fields of engineering. In particular the course presents applications in aerospace, automotive and biomedical engineering.
The knowledge acquired in this course helps the students to handle the electromagnetic compatibility of single systems and especially the integration of systems, allowing their compliance with international (European and worldwide) EMC standards.
Basic mathematical and electromagnetic concepts, together with an intuitive experimental approach, will be used to explain the complex functioning of systems and their sometime unexpected behavior after integration.
The course topics will be presented through applicative examples.
Simple experimental setups with demos will allow the full comprehension of physics phenomena involved in electromagnetic compatibility.
Among the applicative examples we recall: shielding of systems, grounding of complex systems, interference due to artificial high intensity source (localization systems) or natural high intensity source (lightning exposure), coexistence of multi-band radio systems (cellular phones, Wifi, navigation), coexistence with non-electromagnetic systems, flight safety, electromagnetic compatibility in biomedical equipment, biological effects of electromagnetic fields...

The aim is to provide an electromagnetic sensitivity to the system engineer in aerospace, automotive and biomedical engineering.
