Objectives
This course, divided into three parts, aims to provide the basic concepts about the nature and use of electromagnetic fields, which are the basis of wired and wireless telecommunications. The part on the fundamentals of applied optics provide the concepts and fundamentals on lightwaves, their nature, their description and their physical characteristics, it will also illustrate the main areas of application engineering, with particular attention to aspects of telecommunications. The part on the fundamentals of electromagnetic fields and propagation provides the student with the first introduction to concepts related specifically to the theory of electromagnetic fields and will therefore be focused on the theory of propagation of dielectric waveguides and optical fibers. The part on wireless communication networks will present and discuss aspects related to radio and mobile phones, dealing with issues that are fundamental physical layer communications over wireless networks.
