Obiettivi
The objective of this course is to introduce to the students the basics of Theory of Electromagnetic Fields. This course represents a bridge between the courses on Electrical Circuits, which the student has already taken, and all the Electromagnetic Systems he/she will encounter in the 2nd Cycle. On successful completion of this module, the student should be able to describe, using proper mathematical models, wave propagation, wave sources, transmission lines, media properties and energy exchange
Sillabo
- Fundamentals: Electromagnetic Field, Maxwell equations, Constitutive Equations, Boundary Conditions
- Time-varying Fields: Poynting and Unicity Theorems, Complex Vectors and Field polarization, Wave equation, Electrodynamical potentials
- Plane wave: Propagation vector, uniform and non-uniform plane wave, TE, TM and TEM waves, reflection and refraction of plane waves, under perpendicular or oblique incidence
- Transmission Lines: transmission line equations, wave impedance and characteristic impedance, forward and backward waves, reflection coefficient and VSWR, Smith diagram, impedance-matching circuits.
- Free-Space Radiation: Green Function, Vector Potentials, Radiation Condition, Equivalence and Reciprocity Principles, Fundamentals on Antennas
- Guided Waves: Fields in metallic or dielectric waveguides, Propagation Modes, Eigenvalues and Eigenvectors, Cutoff in a waveguide, Rectangular and Circular Waveguides
- Laboratory: Experiments and measurements on wave propagation in rectangular waveguide
