- Electromagnetic compatibility as a method of analysis and design.
Radiated and conducted emissions, Conducted and radiated susceptibility, diaphragm and shielding. Measurement and qualification methods - Reference texts
- 1) Clayton R. Paul “Introduction to Electromagnetic compatibility” Wiley
2) H.W. OTT “Electromagnetic compatibilità engineering” Wiley
3) Morgan “ Handbook for EMC testing and measurement” IET - Educational objectives
- The student will first address electromagnetic compatibility issues with the aim of understanding the solving and qualification methodologies of electromagnetic problems
- Prerequisites
- The student must have achieved capacity of understanding and analysis of problems related to electromagnetic fields and electronic circuits.
Adequate basis for spectral analysis of the signals are strongly recommended. - Teaching methods
- Theoretical lessons and practical training
- Learning verification modality
- The exam includes an oral test and the exposition of a technical report produced independently or in groups.
The oral exam is performed in a discussion lasting about 30 minutes aimed to determine the
level of knowledge and understanding achieved by students on the theoretical content and
methodology listed in program. The oral exam will also test the communication ability of
the student of and autonomous organization exposure on the exame topics or theoretical content. - Extended program
