    Obiettivi formativi

    The course intends to provide an introduction to the nanotechnologies, with
    a particular focus on the photonics
    - Applying knowledge and understanding:
    At the end of the learning process, the students will acquire the basic
    knowledge that is needed to manage a large variety of theoretical tools
    for the design and simulation of photonic devices.

    Prerequisiti

    Adequate knowledge of Quantum Mechanics and electromagnetism

    Metodologie didattiche

    The course is organized in 48 hours of frontal lectures.
    Attendance is not compulsory but strongly recommended.

    Metodi di valutazione

    The examination consists in an oral interview based on the discussion of
    the topics treated during the course, with a typical duration of 40
    minutes. Together with the evaluation of the degree of knowledge and
    understanding reached by the student, the interview is aimed to evaluate
    the students' ability in managing photonic problems.
