Subject fundamentals
Aim of the course (1st semester, 2nd year) is to provide the students of Electronic Engineering and Physical Engineering with the theoretical concepts to be used in all courses of the following semesters. This is therefore a pivotal course for the ensuing career of an electronic engineer and a physics engineer.
The course is divided in two sections: in the first one (Classical Electromagnetism), fundamental subjects of basic physics are treated, such as: electromagnetism and the Maxwell's equations, physical and geometrical optics. In the second section (Introduction to Quantum Mechanics and Structure of Matter), students are divided in two groups, composed of all physics engineers (SQ1) and all electronic engineers (SQ2). For students of Physics Engineering, the subjects involve: the crisis of classical mechanics, the transition to the fundaments of modern physics, with emphasis on quantum physics and its implications in terms of methods and practice. For students of Electronic Engineering, the quantum physics concepts needed to describe electronic and optical properties of matter are developed, with emphasis to the classes of semiconductor and metallic materials.

Delivery modes
Class exercises concern with simple problem solving activities, in strict correlation with the previous theoretical lectures. In some cases scientific calculators (students' personal property) may be required.
Texts, readings, handouts and other learning resources
Classical Electromagnetism:
- "Elementi di FISICA Elettromagnetismo e onde" P. MAZZOLDI, M. NIGRO e C. VOCI -II Edizione (ED. EDISES)
- F. Giorgis’ notes

Introduction to Quantum Mechanics and Structure of Matter:
- Notes by F. Giorgis, C. Pirri and S. Ferrero
Assessment and grading criteria
The exam include a written and an oral proof.
The written proof concerns with: a) multiple-answer quiz on the classical electromagnetism theory, b) questions on quantum mechanics theory, c) problems (either symbolic or numeric) referring to the main subjects of all the course. The maximum mark of the problems section is 15/30, that of the questions section is 15/30. The total scheduled time for the written exam is 2h 30min. The written proof is passed with a total score of at least 18/30.
The oral proof lasts 20-30 mins. and deals with all the subjects treated in lectures of Quantum Mechanics and Structure of Matter.
The final mark is a weighted average of written/oral scores.
Notes

The course is held by two teachers, respectively responsible; (a) for the first part (one class) and the second part (Physical Engineering students) and (b) for the second part ( Electronic Engineering students).
