The aim of this subject is to make students be able to:

- Define and understand terms related to electromagnetic waves, as well as acquire knowledge of new technologies on their own for the development of telecommunications systems. (Competence R1 of the telecommunications module, competence G003 of the degree.)

- Use skills, tools, and applications to solve and develop solutions applied to telecommunications, handling specifications, regulations, and compulsory rules, and understanding the ethical and professional responsibility of a technical telecommunications engineer. (Competence R2 of the telecommunications module, competences G004 and G006 of the degree.)

- Handle, analyse, and specify the basic parameters of electromagnetic waves for its application in communication systems, performing measurements, calculations, and reports, and understanding the propagation mechanisms, the transmission of waves on different media, and the devices used to transmit and receive those waves (Competences R4 and R8 of the telecommunications module, competences G003 and G005 of the degree.)

- Analyse the normal and oblique incidence of plane waves on plane surfaces, and evaluate the advantages and drawbacks of guided and non-guided propagation systems, being able to explain clearly the procedures, results, and ideas related to telecommunications. (Competence R5 of the telecommunications module, competence G009 of the degree.)

Practical laboratory work:

- P1: Measurement of RF signals with the spectrum analyzer

- P2: Measurement of the frequency on waveguides

- P3: Measurement of coaxial cables with the network analyzer

- P4: Measurement of the standing wave ratio on waveguides

- P5: Measurement of antennas

The theory of each lesson is explained using slides in the lectures. There is also available a book of the subject for further reading. These lectures will be complemented by problem-solving activities. The experience gained during the lectures will be applied to the practical laboratory work.

The total score of the subject is divided into two sections:

- 88 % of the total score: assessment of the written exam.

- 12 % of the total score: assessment of the practical laboratory work.



To pass the subject it is required:

- To get a score equal to or greater than 5 points out of 10 on the written exam

and

- to get a score equal to or greater than 5 points out of 10 on the practical laboratory work.



Assessment of the written exam:

- Only final assessment.

* Written exam in the official examination hour: set of problems and/or questions.



Assessment of the practical laboratory work:

- Continuous assessment:

* Reports of the obtained measurements.

* Team work; it is mandatory to submit each report after each session.

* Students have the right to be assessed by final assessment: they must report a written statement for such a claim, with a deadline of 9 weeks, starting from the beginning of the four-month period.

- Final assessment:

* Practical exam after the written exam (in the official examination date).



Declining to sit: not attending the final exam call will be considered equivalent to a withdrawal (no examination attempt is used).

Notes and book of the subject. Slides in PowerPoint. Guide notes and reports of the practical laboratory work. Available at eGela.
