Learning outcomes
The aim of the course is to provide the basic knowledge of electromagnetism in matter and optics, starting from the experimental observation towards the formulation of laws. We intend to provide the student with knowledge on: electric and magnetic phenomena, static and dynamic, in matter; the theory that allows their description, with the formulation of Maxwell's equations in matter; electromagnetic waves and the phenomena of wave and geometrical optics. It is expected that from this and previous courses in general physics, the student will develop skills to understand natural phenomena and widespread applications that can be interpreted even on the basis of classical physics, not requiring quantum theories.
Course contents
Electrical properties of matter: electrical susceptibility, dielectrics and conductors, polarization, electrical displacement, electrostatic energy.
Magnetic properties of matter: magnetic susceptibility, classification of magnetic materials, magnetization, magnetic field, magnetic energy.
Wave phenomena. Electromagnetic waves in vacuum and in dispersive and / or absorbing media: properties and related phenomena.
Physical optics: reflection and refraction; polarization; optical response in anisotropic means; interference; diffraction. Geometrical optics in mirrors, lenses and optical instruments.
Introduction to radiation emission and absorption, and to semiconductor-based electronic and photonic devices.

Assessment methods
The assessment of learning takes place through a written test and an oral exam. The written test aims to ascertain the skills acquired in solving problems within the topics covered in the course: it does not imply a threshold score to allow access to the oral test; its validity is limited to the appeals of the same exam session. In the oral exam the student should demonstrate the knowledge and understanding of phenomena, laws and applications of electromagnetism in matter and optics; the final grade, expressed in thirtieths, takes into account the evaluation reported in both tests.
