Università Roma Tre

The course can be organised into six thematic units, following a progression from electromagnetic fundamentals to the design of the main microwave components.

1. Electromagnetic fundamentals and guided propagation
The first part of the course recalls Maxwell’s equations and their role in the description of guided electromagnetic propagation. The connection between electromagnetic theory and the circuit modelling of high-frequency devices is introduced.
2. TEM transmission lines and distributed circuit model
The second unit deals with transmission-line theory, with specific reference to TEM lines, longitudinal-transverse field decomposition, the main practical types of transmission lines and the distributed circuit model.
3. Terminated lines, reflection and power transfer
The third part focuses on the analysis of terminated transmission lines, reflection coefficient, wave impedance, standing waves, impedance transformation along the line and power transfer from source to load.
4. Impedance matching and microwave networks
The fourth unit is devoted to the basic techniques of impedance matching and to the matrix representation of microwave networks, with particular attention to scattering parameters and their physical interpretation.
5. Multiport components and microwave devices
The fifth part introduces the analysis of three-port and four-port devices and covers the main microwave components: Wilkinson power dividers, hybrid couplers, filters, circulators and small-signal amplifiers.
6. Design exercises and simulation
The final part includes guided analysis and design exercises, also using circuit and electromagnetic simulation tools such as AWR Microwave Office and CST Microwave Studio, applied to matching networks, power dividers, couplers and microwave filters.

Textbooks and teaching materials will be provided by the instructor or indicated during the course among resources available in open access. The material will include lecture notes, exercises, technical documentation and selected references for further study of the topics covered.
