OBJECTIVES:
This course aims to provide the basic principles and models for the representation of electromagnetic transmission and propagation phenomena up to the description of the most common classes of guiding / radiating elements and of the entire wireless communication link.

KNOWLEDGE AND UNDERSTANDING:
Students will have understood the principles and the mathematical representation of transmission, irradiation, propagation and reception of electromagnetic waves. At the end of the course the student: – will know the basic methodologies of problem analysis described by the Maxwell Equations; – will know the solution of Maxwell’s equations in terms of plane waves and the propagation, reflection and refraction modes of the latter; – will know the behavior of transmission lines and will be able to use the Smith diagram; he will know the basic guiding structures and the relative modalities he will be able to characterize the irradiated field at great distance from electromagnetic sources; – will know the descriptive quantities of the behavior of the antennas both in transmission and in reception; –

ABILITY TO APPLY KNOWLEDGE AND UNDERSTANDING:
Students will be able to interpret the most common phenomena of electromagnetic propagation in free space and in material means. They will be able to understand qualitatively and quantitatively the phenomena and the peculiar characteristics of radiant and basic guiding structures. Thanks to the use of basic CAD and Matlab type calculation software they will be able to directly analyze the different phenomena covered by the course.

AUTONOMY OF JUDGMENT:
Students will acquire the ability to integrate the knowledge provided with those found autonomously by accessing the scientific literature / datasheet of components. The autonomous and guided development of exercises (also in Matlab / CAD electromagnetic base) will complete the training.

COMMUNICATION SKILLS:
Students will be able to illustrate in a synthetic and analytical way all the topics of the course using equations and schemes. They will communicate quantitatively the resolution of exercises and complex problems, also through basic electromagnetic Matlab / CAD.

LEARNING SKILLS:
Students will have acquired the ability to read and understand scientific texts and datasheets in English for further information on the topics covered by the course and for the resolution of the exercises.
