Abstract
engineering. This course aims to provide students with a solid theoretical foundation allowing them to
understand the complex phenomena related to wave propagation in various media.
Starting from Maxwell's equations, we explored the fundamental properties of electromagnetic waves,
particularly in vacuum and in dielectric and conductive media. The concepts of plane wave, polarization,
Poynting vector and skin effect were developed in detail.
The study of reflection and refraction phenomena at the interface of two media made it possible to
understand how waves interact with objects and surfaces. These concepts are essential for the design of
wireless communication systems.
Finally, we addressed the specificities of radio wave propagation in the atmosphere, taking into account
the effects of refraction and reflection on the ground. This part of the course is particularly important
for the design of long-range radiocommunication systems.
Students are now able to model, analyze, design and solve problems related to wave propagation in
various communication systems. This course provides a solid foundation for the study of more advanced
topics such as antenna theory, propagation in complex environments (urban, indoor) and radar systems.
In conclusion, mastering wave propagation phenomena is essential for any engineer wishing to contribute
to the evolution of wireless communication syste
