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)

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. This part consists of three questions related to the following three topics: basic of em theory; free-space propagation and reference models; guided propagation
To pass this part it is mandatory to achieve a sufficient level of confidence on the above-mentioned subjects.

•Practical part (either committed to a group of students or to a single student) where one needs to comment and discuss selected laboratory practical experiments undertaking during the course and numerical experiments undertaken using Matlab developing tool.
To pass this part it is mandatory to demonstrate a sufficient ability in describing the experiments and linking the results to the theoretical facts.
The final grade is the weighted sum of the two scores (70% oral and 30% practice).
In case one of the two tests is unsatisfactory or the global grade is below 18, the student has to repeat the two tests.
