The course is the first contact of the student with the concepts of electromagnetism
(E/M) and optics. The course aims at introducing students to the basic properties of
electromagnetic fields in terms of both their static form and their dependence on
their respective sources, charges and currents, as well as the E/M interactions when
the fields are time dependent and charges or current carrying wires are moving in
magnetic fields. At the same time, through the properties of the Electromagnetic
Field, the students are familiarized with the use of analytical mathematical tools
(integral and differential calculus), through the formulation of laws of the
electromagnetic field (Maxwell’s laws), and through their applications to elementary
Electrostatic- Electro-Induction problems and the introductory description of the
E/M waves.
Finally, a small part of the course is devoted to introducing students to geometric and
wave optics.
