Course Objectives
Electromagnetic compatibility is the discipline that studies the electromagnetic interactions between electrical and electronic equipment and systems. The basic objectives are to "identify and simulate the sources of interference that characterize the electromagnetic environment in which the various devices are immersed, to determine the possible couplings and interference generated, to identify protective devices, and to define design constraints. The analysis tools are based on the theory of electromagnetic fields and electrical circuits. This knowledge is of fundamental interest to the electrical and electronic engineer.
Course Prerequisites
To attend the course and take the exam, it is necessary to have understood and studied the contents of the courses in: Mathematical Analysis, General Physics.
Teaching Methods
Lectures are delivered in a face-to-face teaching mode. Lectures will also be delivered with the use of teaching aids. Computer-guided exercises are scheduled.
Assessment Methods
The exam consists of an oral test accompanied by the discussion of a paper accompanied by a series of
codes written in the Matlab programming environment, related to each of the topics covered in the
course. The paper is designed to assess the student's ability to apply the knowledge acquired during the course
to problem solving. The oral exam is designed to determine the level of knowledge and understanding of the course content,
to assess independent judgment, learning and communication skills, and will consist of a discussion of
the written exam, questions and/or exercises related to the course content.
The final grade for the examination papers will be determined on the basis of both the written paper and
the oral examination.
The evaluation grid adopted is defined as follows:
If the student demonstrates a basic knowledge of the main topics, a basic grasp of the technical
language, sufficient interpretive ability, and sufficient ability to apply the basic knowledge acquired the
score achieved will be between 18 and 19;
If the student demonstrates adequate knowledge of the topics but limited mastery of them, satisfactory
ownership of language, correct interpretive ability, more than sufficient ability to apply the knowledge
independently to solve the proposed problems the score achieved will be between 20 and 23;
If the student demonstrates knowledge of the topics with a good degree of mastery, satisfactory
ownership of language, correct and confident interpretive ability, and a good ability to apply most of the
knowledge correctly to solve the proposed problems the achieved score will be between 24 and 27;
If the student demonstrates a complete and thorough knowledge of the topics, excellent ownership of
language, complete and effective interpretive ability, and is able to independently apply the knowledge
to solve the proposed problems the score achieved will be between 28 and 30;
The score of 30 with honors will be achieved by the student who is able to demonstrate complete,
thorough and critical knowledge of the topics, excellent language property, complete and original
interpretive ability and full ability to independently apply the knowledge to solve the proposed problems.
