Theory of Electromagnetic Field B
- Department of Electromagnetic Field
This course presents fundamentals of electromagnetic field theory and its applications. Analysis methods proper for
static, stationary as well as dynamic fields and waves in free space and on basic transmission lines are presented as well.
This course provides students with physics - based wiev on studied effects, which is applied then on engineering
problems. At the end of the course, all effects should not only be described, but quantified as well. Basic knowledge and
insight into communication devices, systems and techniques is provided, applicable not only to systems currently taught
in other courses, but to future systems as well.
