Basis of industrial and environmental electromagnetic compatibility- Reference texts
Clayton R. Paul “Introduction to Electromagnetic compatibility” Wiley
H.W. OTT “Electromagnetic compatibilità engineering” Wiley
Morgan “ Handbook for EMC testing and measurement” IET- Educational objectives
Electromagnetic compatibility in an industrial environment
The main instruments of electromagnetic compatibility
noise mitigation techniques
emission measurement techniques
test methods- Prerequisites
Course skills of:
Circuit theory, Electromagnetic fields, Antennas- Teaching methods
lessons and laboratory exercises- Other information
- Learning verification modality
The exam includes an oral test and the presentation of a technical report produced independently or in a group.
The oral test consists of a discussion lasting about 30 minutes aimed at ascertaining the level of knowledge and understanding achieved by the student on the theoretical contents and
methods indicated in the program. The oral test will also enable students to verify the student's communication skills with language properties and autonomous organization of the exposition
on the same topics or theoretical content.- Extended program
