LEARNING GOALS 
The aims of the course are: to provide the students with the methodological tools and the basic knowledge necessary for the study of the properties of electromagnetic fields, in relation to the problems of free-space and guided propagation and radiation; to provide the students with the methodological and operational tools for the study of guided electromagnetic propagation and for the characterization and use of transmission lines and wave guides, with reference to the most important application problems.

EXPECTED LEARNING OUTCOMES (DUBLIN DESCRIPTORS) 

Knowledge and understanding 
The student needs to show ability to know and understand problems related to the foundations of applied electromagnetism, guided propagation and radiation. In this sense, the course aims to provide students with basic knowledge and methodological tools essential to understand the phenomenology and the functioning of elementary systems for electromagnetic links. 

Applying knowledge and understanding 
The student needs to show that he is able to use the acquired knowledge for the analysis of some simple electromagnetic systems, applying it concretely to the solution of elementary problems of guided propagation.

TEACHING METHODS 
Teacher/s will use: a) lectures for about 75% of total hours; b) practical exercises for about 25% of total hours.   

EXAMINATION/EVALUATION CRITERIA 
For integrated courses, this field should encompass all modules, with indication of the relative weight of each module on the final mark. For integrated courses, this field should be coordinated by the reference teacher for the course. 

Exam type:

• Written and oral.

In case of a written exam, questions refer to:

• Numerical exercises.

Evaluation criteria:
This field needs to be filled in only when there are different weights among written and oral exams, or among modules if this refers to an integrated course.
