INDUSTRIAL ELECTROMAGNETIC COMPATIBILITY
Academic Year 2024/2025 - Teacher: Nunzio SALERNOExpected Learning Outcomes
Industrial electromagnetic compatibility is based on the study of the effects of electromagnetic fields created by electrical devices and on the design of systems to reduce their impact on themselves, other devices, or human beings.
Knowledge and understanding.
The course aims to provide basic knowledge on analytical models and technical aspects related to electromagnetic compatibility (EMC): radiated and conducted emissions, crosstalk, electromagnetic shielding, EMC governmental European requirements for commercial products, EMC measurements for verification of compliance, system design for EMC.
In the laboratory, then, the student will acquire the ability to use software for the numerical solution of electromagnetic field problems by simulating simple devices that are sources of electromagnetic disturbances and applying the related solutions to reduce them.
Applying knowledge and understanding.
At the end of the course, the student will have an overview of the problems related to the design of electromagnetically compatible devices and the leading solutions he can apply to solve them.
Making judgments.
The student will be able to critically observe an electromagnetic device from the point of view of its electromagnetic compatibility and autonomously assess the presence of possible sources of electromagnetic disturbances already in the design phase. This capability is enhanced thanks to the possibility of predicting the device's electromagnetic behaviour through numerical simulations.
Communication skills.
The student will acquire the technical language of electromagnetic compatibility. They will also be able to communicate the design choices to reduce electromagnetic disturbances. The oral exam will allow students to refine their technical language and communication skills.
Learning skills.
The student will be able to learn the causes and solutions of industrial electromagnetic compatibility problems by studying the recommended texts and teaching material provided. Furthermore, thanks to the peculiarity and transversality of the topics covered, the student will improve the ability to learn the various issues while maintaining an interdisciplinary vision.

Learning Assessment
Learning Assessment Procedures
Oral exam.
Booking for the exam session on the SmatEdu platform is mandatory. After having booked, the student must send an email to the teacher to fix the appointment for the exam.
The oral exam typically consists of 3 questions, the first chosen by the student.
The evaluation considers the knowledge of the topics of the course program, the rigour and clarity of presentation, and the ownership of the technical language used.
The oral exam lasts about 30 minutes.
Learning verification can also be carried out remotely, should the conditions require it.
Examples of frequently asked questions and / or exercises
Transmission Lines and Signal Integrity: ringing and clock skew.
Antennas: effects of balancing and baluns.
Nonideal Behavior of Components: inductors, common mode choke.
Radiated Emissions: simple emission models for wires and PCB lands.
Conducted emissions: line impedance stabilization network.
Filters: filter approximations.
Crosstalk: shielded wires.
Shielding effectiveness: near-field sources.
Electrostatic Discharge (ESD): susceptibility to ESD fields.
