Theory of Electromagnetic Field

The course is a substitute for:

Theory of Electromagnetic Field (X17TEP)

Lecturer:

Jan Macháč (gar.)

Tutor:

Jan Macháč (gar.)

Supervisor:

Department of Electromagnetic Field

Synopsis:

This course brings information on electromagnetic field computation, forming the starting ground of many other subjects and is the necessary part of the knowledge of any electro-engineer. Based on fundamentals, students learn basic characteristics and solution methods of static, stationary and time varying fields. Methods for capacitor, inductor, line, magnetic circuits and transformer design are presented togheder with wave propagation in a free space and different lines.
