Objectives

The course objective is to give the basic knowledge required to understand, analize and design ICT and electronic systems based on the use of electromagnetic field at RF and microwave frequencies.
The course takes an approach strongly model-oriented, based on a firm knowledge of math and physics. One of the main focus id the build-up and solution of models of those systems, mainly related to radio communications.
To be more detailed, the student will acquire a good knowledge of the Electromagnetic Engineering topics, and will be able to use them to identify, model and solve some important engineering problems related to the propagation of EM waves and to the pertinent electronic devices, maily distribuited circuits and antennas, and their integrations.
Course objectives:
Knowledge and Understanding: In addistion to a basic knowledge of the properties of EM fields, the students will be able to evaluate correctly the effects of the EM phenomena on ICT and electronics systems.
Such a knowledge is needed to face the more advenced topic related to the design of the EM part of such systems. But is useful also to designer of the other parts of electronic systems both for ICT and for biomedical and physical measurements, since they will able to interact in an effectve way with the designers of the EM part.
Applying knowledge and understanding: the chosen approach has a twofold way of application. On one side, to give students the basic skills to apply standard solutions. On the other, the ability to build-up a suitable and effective model of a physical situation, to solve it and to get a physical insight from the found solution.

Prerequisites

A good knowledge and abilities in college math and physics and in applied math (with a focus on differential and integral calculus in 1,2,3 variables, vector algebra and analysis, complex number and complex exponentials, simple differential equations, Fourier transform) are required to face the course.

Moreover, the course require a good knowledge, ability and competencies on circuit theory, above all on AC circuits.

Contents

The syllabus is as follows.
Maxwell equations and theorems (lectures: 10h, numerical applications: 2h): Maxwell equations, materials, energy and power theorems, reciprocity, equivalence, uniqueness.
Plane wave propagation (lectures: 8h, numerical applications: 6h): plane waves, polarization, propagation in material media, group speed, plane interfaces.
Transmission lines and matching networks (lectures: 14h, numerical applications: 14h): propagation in ideal transmission lines, maximization of load power, non-ideal transmission lines.
Antennas and radio-links (lectures: 15h, numerical applications: 9h): elementary sources, Green function, effective height and gain, wire antennas, receiving antennas, free-space radio links, antennas on the ground, RFID.

Teaching Methods

The development of classroom lectures will be organized so that all topics will be connected in an unique discourse. In this way, the reasoning abilities of the students will be developed. The connections with other courses, or with the professional activities, will be enlighted. The numerical applications will focus on the ability to build up a suitable model of the object (or phenomenon), and to solve it to get the required results.
The first week or so of lectures will be devoted to summarize the main results of vector algebra and analysis, and of complex number computations. The knowledge of these topics will be tested before, and after, these lectures.

Verification of learning

The final verification consists of a written part and an oral exam. The written part is based on analysis and synthesis problems.

More Information

All the lecture notes will be available, togheter with the numerical exercises developed.
A number of further exam problems will be given, too. Some of them will be complemented with full solutions, or hints fo solutions, while other contains only some results, or hint for solution, or none at all, to allow students to develop their own procedures and become able to assess the relative correctness.
To pass the exam, a good level of knowledge and abilities, and a minimum level of competencies, are required. The final mark increase with the abilities, and, above all, competencies, shown by the student.
It is clear that knowledge and abilities are verified by both the written and the oral exam, though they test different kind ob abilities. To pass the written exam with a minimum result requires also some competencies, and the ability to divide a problem in smallest (and simpler) part, an ability which is fundamental in all engineering problems. An higher mark, on the other hand, requires a good level of competency.
