Presentazione
The course is taught in English.
The transport of information, in any electronic or photonic system, always occurs through the propagation of electromagnetic waves. These phenomena are completely described by Maxwell's equations, whose methodological study constitutes a fundamental point of the curriculum in electronic and telecommunications engineering. In addition to the classic applications in the field of radio frequency, microwave, millimeter-wave and optic communications, the continuous growth of electronic technology makes it necessary to consider properly the electromagnetic phenomena in the design of almost all the electronic components and subsystems.
Risultati di apprendimento attesi
Knowledge of the phenomena associated with dynamic electromagnetic fields, and in particular with time-harmonic fields, for the most relevant applications of information engineering: electronic components and subsystems for RF, microwave and millimeter waves, and wireless propagation at-large.
Ability
- to apply analytical methods to the system analysis
- to apply simple design techniques to the above-mentioned applications of the electromagnetic fields
- to measure scattering parameters using the vector network analyser
- to measure an antenna radiation pattern and gain
Prerequisiti / Conoscenze pregresse

Programma
Transmission lines and distributed parameter components (3 CFU): line equations and their solution; Smith chart; impedance matching; scattering parameters and scattering matrix; transmission line transients.
Maxwell equations (1 CFU).
Electromagnetic wave propagation in homogeneous media: plane waves (1 CFU).
Electromagnetic wave radiation and antennas (3 CFU): radiation in free-space; antenna characteristic parameters, radio-link budget; introduction to antennas; dipoles; aperture antennas; arrays (basics).
Organizzazione dell'insegnamento
Lectures and practice classes are used to obtain the expected learning outcomes in terms of knowledge and ability to analyze and design systems. Homeworks will be assigned. To foster the learning and provide practical abilities, experimental labs are organized on the measurements of scattering parameters for microstrip components using the vector network analyser and on the measurement of antenna radiation pattern and gain.
