Obiettivi dell'insegnamento

The course builds on basic principles and concepts (in the field of electric circuit analysis, signals and systems, electronics, and electromagnetic fields) to provide an introduction to Electromagnetic Compatibility (EMC). The course is designed to help students develop a deeper understanding of electromagnetic interference and the prevention of it through suitable design strategies. The addressed subjects cover: nonideal behavior of components, transmission line circuit models for EMC, conducted emissions and susceptibility, radiated emissions and susceptibility, antennas (basic principles, test and measurement antennas for EMC), crosstalk, shielding, grounding, measurement instrumentation, setups and facilities for EMC testing, governmental and functional requirements, system design for EMC. Practical applications considered in this course concern EMC aspects in complex electrical and electronic systems and environments, such as those found in aerospace, automotive, electric power generation, transmission/delivery, and railway industry sectors.

The teaching activity of this course includes lecture hours, training sessions, and lab sessions. Expectations of achievements and abilities resulting from a successful attendance of this course are those associated with the Dublin Descriptors DD1, DD2, DD3, DD4.

 

Notes:

  1. This course allows students to gain background knowledge to access the course on Signal and Power Integrity of High-Speed Printed Circuit Boards (elective, extracurricular, 30-hour teaching module belonging to the Innovative Teaching Course Basket of Polimi, run in collaboration with ICT companies).
  2. The 8-credit course Electromagnetic Compatibility A (093576) is offered jointly with course Electromagnetic Compatibility B (093589). These courses have the same learning outcomes and associated competence levels. The only difference concerns course contents. Course EMC A does not include the parts on (a) electromagnetic field equations and waves and (b) two-conductor transmission lines. For students taking the 8-credit course, these parts are considered as prerequisites.

Risultati di apprendimento attesi

Lecture hours will allow students

  • to know and understand (DD1):
    • the most important electromagnetic interference phenomena. Particularly, to know and understand the four basic EMC subproblems (i.e., radiated emissions; radiated susceptibility, conducted emissions, and conducted susceptibility) and their role on the design of electrical and electronic systems
    • the basic principles of the measurement procedures and setups for EMC assessment
  • to apply knowledge and understanding (DD2, DD3):
    • to lumped or distributed-parameter circuit models as well as electromagnetic models for the prediction of EMC behavior of electrical/electronic systems
    • to identify the dominant effects in EMC problems, and to orient the design of an electrical/electronic system toward EMC compliance.

 

Training sessions will allow students (DD1, DD2, DD3):

  • to become familiar with the theoretical concepts presented during lecture hours (DD2, DD2)
  • to learn how to work with numerical tools for circuit simulation and electromagnetic analysis in order to develop EMC prediction models
  • to predict and assess nonideal behavior of circuit components
  • to design and analyze power supply filters
  • to design wired interconnections minimizing crosstalk
  • to predict the effect of field-to-wire coupling as well as radiated emissions in wiring structures
  • to analyze and design simple shielding structures.

 

Lab hours will allow students (DD2, DD4) to understand how instrumentation and special facilities can be used for EMC model extraction, as well as for EMC pre-compliance and compliance testing.

Prerequisiti

The prerequisites are the completion of the basic undergraduate electrical engineering courses in electric circuit analysis, signals and systems, electromagnetic fields and transmission lines. The course builds on those basic skills, principles, and concepts and focuses on EMI phenomena.


Modalità di valutazione

Classroom assessment will be based on homework (exercises and short project/s) and end-of-course examination (written test).

Homework

During the course, three sets of exercises and/or problems (involving both theoretical work and use of electromagnetic simulation tools) will be proposed as homework to students. In this activity, students will interact and be assisted by instructors (tutoring sessions), and will be required to submit homework reports. The three homework sessions will be ranked Pass/Fail. The end-of-course examination will be accessible only if all homework sessions are successfully passed.

Homework is intended to deepen subjects developed and discussed during classroom hours (DD1, DD2). At the same time, it is aimed at encouraging proactive approach of engaged students who care about their learning. It enhances team working skills, help developing ability to make judgements, and improves communication skills (DD3, DD4).

End-of-Course Examination

The end-of-course examination is a comprehensive exam aimed at assessing the examinee's knowledge of basic EMC concepts and his/her ability to solve simple EMC problems. It is in the form of a written test composed of two parts: a) multiple-answer questions and b) problems/exercises (numerical and/or literal solution required).

The written test is aimed at evaluating (DD1, DD2):

  • knowledge and understanding of key concepts in EMC (multi-answer questions),
  • ability to apply knowledge and understanding of EMC concepts to simple problems by: (a) resorting to a logical and tidy approach, (b) showing ability to identify dominant EMC phenomena and focus analysis on fundamental aspects.

No oral examination is foreseen.
