Course description

This is a course that belongs to the field of applied electromagnetics (ING-INF/02 – Electromagnetic fields). The course aims at providing advanced knowledge of electromagnetic wave propagation. Both guided and free propagation will be addressed.

Knowledge and understanding:
The student is expected to achieve an advanced knowledge key mechanisms that govern free and guided propagation of electromagnetic waves.

Applying knowledge and understanding:
The student is expected to achieve an advanced knowledge with respect to propagation scenarios involving free propagation and guiding structures characterized by rectangular and circular shapes.

Judgement skills:
The student is expected to identify the challenges that characterize free and guided propagation in order to provide the best technological solution for a given actual problem.

Communication skills:
The student is expected to explain the electromagnetic rationale that lies at the basis of free and guided propagation using a clear and effective technical language.

Learning skills:
The student is expected to achieve a self-understanding stage to update his knowledge using different sources, e.g. books and scientific papers, and to achieve a deeper knowledge of the field, being able to follow master courses within the ICT field.

Prerequisites

Although there are no formal prerequisites, the basic knowledge of electromagnetic fields is recommended:
•Maxwell’s equation and plane wave solution
•Plane waves properties
•Polarisation
•Reflection, refraction and diffraction

Syllabus

1. Introduction and basics of electromagnetic fields (~6h traditional lectures + 4h practice)
o Maxwell’s equations
o Plane waves and their characteristics
o Plane wave classification
o Electromagnetic waves propagation: practical examples.
O Reflection
5. Free propagation (~6h traditional lectures + 4h practice)
o Direct, reflected, diffracted and scattered waves.
o Plane Earth model.
o Spherical Earth model.
o Fresnel’s zones.
o Equivalent Earth radius
o Super-refraction.
o Tropospheric scattering.
o Fading.
o Ionospheric phenomena.
3. Transmission lines (~8h traditional lectures + ~4h practice)
o Lumped element model.
o Voltage and current.
o Characteristic impedance.
o Phasor regime.
o Travelling and stationary solutions
o Reflection coefficient.
o Standing wave ratio (SWR)
o Input impedance.
o Loss-less and lossy transmission lines.
o Introduction to matching.
o Smith Chart.

4. Waveguides (~10h traditional lectures + ~6h practice)
o TE-TM decomposition.
o Eigenvalue equation.

o Rectangular waveguide.
o Circular waveguide.
o Coaxial cable.

The course consists of 48h: 32h of traditional lectures and 16h of practice. The latter include both laboratory experiments, undertaken using the anechoic and reverberating chambers, and numerical simulations in Matlab environment.

Learning assessment

The examination aims at verifying the previously stated educational targets. The examination consists of two parts that take place within the same day.
•Oral exam that aims at evaluating the student’s ability to link and analyze the topics studied during the course; the minimal score to pass the test is 12/20;
•Group project where students (2-3 student per group) needs to comment and discuss selected laboratory practical experiments undertaking during the course and numerical experiments undertaken using Matlab developing tool.
The final grade is the sum of the two scores. In case one of the two tests is unsatisfactory or the global grade is below 18, the student has to repeat the two tests.
