Electromagnetic fields

The course in 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 all 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.

Electromagnetic fields

1. Measurements of scattering parameters for microstrip components with network analyser. (descriptive) 2. Measurements of scattering parameters with the slotted line. 3. Measurement of antenna radiation pattern.

Electromagnetic fields

The course consists of lectures and classroom exercise sessions, as well as laboratory exercises following the program of the main lectures. The laboratory exercises concern instead the analysis of the scattering parameters of some components in microstrip and the simulation of the radiation pattern of some simple antennas. Throughout the duration of the course will also be proposed exercises to be carried out at home and to be delivered in electronic format to obtain an additional bonus in the exam.
