Learning Objectives
Provide the basics on the propagation of an electromagnetic wave in homogeneous and non-homogeneous guiding structures, and on the functioning of microwave and millimeter waves devices.
Prerequisites
* Electromagnetic Fields
* Antennas and Propagation -or- Electromagnetic Waves Theory and Technique
Teaching Methods
Ex-cathedra lectures
Type of Assessment
Oral examination. As a first step the candidate will be asked to describe how a specific device works. Then, several questions will be asked about all parts of the course syllabus.
