Course description

This course belongs to the disciplinary scientific sector ING-INF/02 – Electromagnetic fields. The course aims at providing advanced knowledge of electromagnetic compatibility. Performance implications with reference to operational context 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 electromagnetic compatibility and its regulations, being able to follow technical courses and seminars on the topic.

Prerequisites

There are no formal prerequisites. Nonetheless, the basic knowledge of main topics related to the electromagnetic fields (including antennas and propagation), together with fundamentals of circuit and signal theory is recommended.

Syllabus

1. Introduction and course presentation: introduction to electromagnetic compatibility, typical problems in electromagnetic compatibility, course overview and organization.
2. Recalls and basics of electromagnetic compatibility: electric dimensions, use of decibels, power evaluation along transmission lines, typical measurement setups.
3. Analysis of typical EMC signals in the frequency domain: signal characterization in time and frequency domains, Bode diagrams and envelopes, basics on how to use the spectrum analyzer.
4. Non-ideal behavior of passive components and their use as suppressors of disturbances: models for transmission lines: wires and lands on printed circuit boards, component leads, evaluation of internal and external electric parameters, lumped-parameters equivalent circuits, ideal and actual Bode diagrams: resistors, capacitors and inductors, high-frequency disturbances suppression, ferromagnetic materials and ferrite beads, common-mode chokes.
5. Radiated and conducted emissions and susceptibility: near and far field, common- and differential-mode currents, radiated emissions for transmission lines, current probes, susceptibility models for wires and lands on printed circuit boards, LISN for conducted emissions, power supply filters, power supplies, conducted susceptibility - showcases.
6. Crosstalk and shielding: crosstalk for transmission lines - time and frequency domain, crosstalk for transmission lines - exact and approximated solution, weakly coupled transmission lines - inductive, capacitive and common-impedance coupling, crosstalk reduction - shielded and twisted wires, shielding factor and effectiveness, effects of non-ideal components on shielding effectiveness, exact and approximated solution for shielding in case of far field sources, approximated solution for shielding in case of near field sources, shielding of low-frequency magnetic fields.
7. EMC measurement standards and regulations: measurement standards, field measurements, regulatory approaches to radiated and conducted emissions and susceptibility, human exposure to electromagnetic fields.

The course consists of 48h that include 32h of traditional lectures and 16h of practice. The latter include laboratory sessions in anechoic and reverberating chambers, guided analysis of actual experimental data and technical seminars. The main topics addressed during the course are summarized as follows:

1. Introduction and course presentation (~2h traditional lesson)
2. Recalls and basics of electromagnetic compatibility (~6h traditional lesson)
3. Analysis of typical EMC signals in the frequency domain (~2h traditional lesson + ~2h practice)
4. Non-ideal behavior of passive components and their use as suppressors of disturbances (~6h traditional lesson + ~2h practice)
5. Radiated and conducted emissions and susceptibility (~6h traditional lesson + ~6h practice)
6. Crosstalk and shielding (~8h traditional lesson + ~4h practice)
7. EMC measurement standards and regulations (~2h traditional lesson + ~2h practice)

Teaching Methods

Traditional lectures, practice, technical seminars.

Textbooks

The suggested teaching support material consists of teacher's slides made available on both the dedicated course page on the MS Teams platform and the e-learning University website (elearning.uniparthenope.it). The following textbooks are suggested: C. R. Paul, "Compatibilità Elettromagnetica: concetti fondamentali di elettromagnetismo – applicazioni progettuali", Hoepli; H.W. Ott, "Electromagnetic Compatibility Engineering", Wiley.

Learning assessment

The examination aims at verifying the previously stated educational targets. The examination consists of an oral exam that aims at evaluating the student’s ability to link and analyze the topics studied during the course and to address typical practical problems of electromagnetic compatibility.

More information

The teacher will be available to support the students during the course every Wednesday (9-11) and Friday (11-13) in his office (Engineering Department, Centro Direzionale isola C4, fifth floor, south side, room 509).
However, the teacher follows an open door policy allowing students to come and ask questions depending on their requests and his availability.
