2. establish the connection between the macroscopic Maxwell equations in matter and microscopic models of matter;
3.  apply the laws of electromagnetism to a large variety of electromagnetic phenomena;
4. master in the resolution of problems a number of mathematical techniques which are tailored to symmetries of the electromagnetic configurations of the considered systems;
5. identify a variety of descriptions and a diversity of expressions for the equations of electromagnetism;
