Students of this subject will be able to:

- Define and understand 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.)

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

- Handle, analyse, and specify the basic parameters of electromagnetic waves for their 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.)

- 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.

Students of this subject work individually or in groups. On one hand, students work individually in the lectures + practical classroom work; on the other, they work in groups of five or six in the practical laboratory work. The methodology is explained in more detail below:

- Lectures: theoretical basics and concepts are explained using PowerPoint presentations.

- Practical classroom work: problem-solving activities are carried out; these problems are related to the theory explained in the lectures.

- Practical laboratory work: experimental measurements are performed and processed, and then recorded in standard reports, in groups of five or six.

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

- 88% of the total mark: assessment of the lectures + practical classroom work.

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



To pass the subject it is required:

- To get at least a 50% pass mark on the lectures + practical classroom work

and

- to get at least a 50% pass mark on the practical laboratory work.



Assessment of the lectures + practical classroom work:

- Continuous assessment:

* Questionnaires in the eGela platform (18% of the total grade).

* Set of problems and/or questions in a final written exam in the official examination date of the final assessment test (70% of the total grade).

* Students have the right to be graded by final assessment: they must present a written request to do this, within 9 weeks, starting from the beginning of the four-month period.

- Final assessment:

* Set of problems and/or questions in a final written exam in the official examination date of the final assessment test (88% of the total grade).



Assessment of the practical laboratory work:

- Continuous assessment:

* Standard reports of the measurements obtained (12% of the total grade).

* Students work in groups and each report must be submitted after each session.

* Students have the right to be graded by final assessment: they must present a written request to do this, within 9 weeks, starting from the beginning of the four-month period.

- Final assessment:

* Practical exam after the written exam in the official examination date of the final assessment test (12% of the total grade).

* Individual.



Withdrawal from a call: non-attendance at the exam call in the official examination date of the final assessment test will result in a withdrawal (NOT PRESENTED will be applied).

Lecture materials and notes are available in the eGela virtual platform:
- PowerPoint slides used in the lectures.
- Questions from the exercises worked on in the practical classroom work.
- Manuals and standard reports of the practical laboratory work.

Information about the use of materials, media and resources:
- During teaching activities (continuous assessment):
* No telephone systems, devices or any other type of help are permitted, except as provided for below.
* Students are permitted to use books or course notes as well as electronic or computer systems or devices. Should these systems or devices have access to the Internet, any search for other than instructional materials will be prohibited.

- In the final assessment test (both continuous assessment and final assessment):
* Neither books or course notes nor telephone, electronic or computer systems or devices nor any other type of help are permitted, except as provided for below.
* Students are only permitted to use calculators.
