Learning unit contents

In this course, we present the foundations for electrostatic, magnetic or electromagnetic fields. The notions are illustrated in the context of different applications, including wave propagation in transmission lines, in waveguides, or optical fibers.
The approach used is progressive: the concepts are first analyzed, interpreted, and illustrated in the context of a simplified application. The results are then exploited for solving more complex problems.
This approach puts forward the difficulties arising in: - manipulating the mathematical formalism (vector calculus, phasors, primitivation) - giving a physical interpretation of the studied phenomena - formulating and interpreting simplifying hypotheses - using different solving methods.
The following elements are studied:
fundamental equations of electrostatics, magnetostatics, Maxwell equations, wave propagation in a dielectric medium, in a dissipative medium, transmission lines (frequency and temporal domains), waveguides.
Questions related to field diffusion (losses) in materials (eddy currents, skin effect), as well as polarization, are also adressed.

Learning outcomes of the learning unit

To be able to:
- formulate the fundamental equations of electromagnetism and explain the underlying physics
- use algebra, vector calculus and primitivation methods that are necessary for solving electromagnetic problems
- decompose a complex problem into simpler ones while identifying the chain of cause/effect
- understand the main technical constraints arising in the design of electromagnetic systems
The frequent practice of homework exercices enables the student to acquire the autonomy and easiness that are necessary for overcoming the difficulties of the course.

Prerequisite knowledge and skills

Parts of the course refer to basic notions of electrical circuit analysis. Notes recalling the needed basic concepts will be made available.

Planned learning activities and teaching methods

The course includes "ex-cathedra" sessions and practice sessions.
The "ex-cathedra" sessions are devoted to the descripton of theoretical concepts, the presentation of the related mathematical concepts, and the description of the physics of the underlying mechanisms.
The practice sessions consists in solving different problems, discussing different solving methods, as well as their limitations.
An elective session of "Questions and answers" is suggested at the end of the quadrimester.

Assessment methods and criteria

Below you will find information on the evaluation methods planned for in-person and remote exams as well as those planned for hybrid sessions. Depending on how the health crisis evolves, the chosen method will be communicated to you no later than one month before the start of the exam session.

Any session :

- In-person

written exam ( open-ended questions )

- Remote

written exam ( open-ended questions )

- If evaluation in "hybrid"

preferred in-person
