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.
