Course contents
Definition of cylindrical structure homogeneous, inhomogeneous limited or unlimited in the transverse direction. Formulation of the Maxwell equations in terms of the modes. Definition of the law of propagation axial. TEM, TE and TM modes. Analytical solutions in major structures: slab planar, rectangular waveguide, coaxial cable. Electric and magnetic modes functions. Full-wave simulation and analysis of the same quantities and characterization of lectric and magnetic field force lines. Definition of the cutoff frequency. Dispersion curve. Dielectric waveguides. Quasi-TEM modes and technologies used: the microstrip and co-planar waveguide. Rigorous derivation of the equivalent circuit and its parameters. Multi-conductor lines: symmetrical coupled lines, odd and even modes. Definition of the scattering matrix and its parameters for electrical networks, even in multi-modal regime. Design of simple circuits in the transmission line and their realization in microstrip technology. the problem of matching a load and study of the Smith chart.
Teaching methods
Lessons based on slides available to the students. The last lessons are taken in the lab where the students practice their theoretical studies by designing simple transmission lines-based circuits.
Assessment methods
Oral exam preceded by a practice text in the lab carried out with a circuit simulator.
