Course program
1. Elements of High Frequency Circuit Theory (20h).
Advanced concepts of guided propagation, modes of propagation in tubular structures - waveguides - and printed - microstrip, coplanar waveguide.
In detail:
Review of free space propagation and guided propagation, Transversalization of Maxwell's equations, TEM, TE and TM modes; Rectangular, circular and coaxial cable waveguides; Planar structures: Microstrip, Coplanar Guide; High frequency circuits: Y, Z, S and ABCD matrix representations of high frequency devices, examples of passive devices in liquid and microstrip (dividers, ladder networks, circulators etc.)
2. Elements of numerical techniques (20h).
Solution of Maxwell's equations in differential form using numerical techniques, with comparison between the various techniques and identification of the most suitable for a given problem.
In detail:
Finite Differences; Finite Elements; Finite Volumes
3. Laboratory: Design, Realization and Characterization of a device (20h)
Design, numerical analysis realization and measurement of a microstrip filter or other device seen in part 1. The exercises are done by dividing the students into groups of 2, maximum 3 so that everyone actively participates in the project.
In detail:
Device design given appropriate specifications; verification of the project, and possible tuning, through circuit simulation in Matlab; simulation through commercial full wave CAD of the device and related tuning; creation of print masks, device printing, connectorization; device measurement via network analyzer.
