Educational objectives
The course introduces the methods and techniques used in the industrial field for the utilization of electromagnetic fields and microwaves. The objective is to prepare the student to address the challenges and identify the best technologies and applications of microwave devices in an industrial context.
Course skills of:
Circuit theory, Electromagnetic fields
Teaching methods
Lectures and laboratory exercises.
Learning verification modality
The examination consists of an oral test and the presentation of a technical paper produced independently or in a group.

The oral test involves a discussion lasting approximately 30 minutes, aimed at assessing the student's level of knowledge and understanding of the theoretical and methodological contents outlined in the program. The oral test will also evaluate the student's communication skills, including language proficiency and the ability to independently organize and present the same topics or theoretical content.
