Subject fundamentals
The aim of the course is to introduce the main physical principles related to classical electromagnetism, including the propagation of light considered as an electromagnetic wave. The course provides insights on multidisciplinary topics related to electromagnetism giving special emphasis on the description of the experimental concepts and to several technological applications.
Expected learning outcomes
The goal is the acquisition of the basic principles related to electromagnetism, electromagnetic waves and optics.
The fundamental applications of each law are shown with the aim of providing the student with a method for the interpretation of the physical phenomena which are at the basis of many engineering problems.
Ability to set up and solve physics problems at intermediate level, in the field of electromagnetism and waves.
Prerequisites / Assumed knowledge
- The subjects and the methods studied in Physics I Course (mechanics and thermodynamics)
- Basics of mathematics and geometry (vector calculus, differential and integral calculus)

Assessment and grading criteria
The exam involves a written and an oral proof. The written proof includes simple problems (either symbolic or numeric) and questions about all the subjects of the course. The total allotted time is 2 hrs. The written proof is passed with a total score of at least 18/30. The oral proof is about all subjects treated in lectures. The final mark is a weighted average of written/oral scores.
