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.

Syllabus of lectures:

1. What is Field Theory good for. Basic laws of electromagnetism

2. Maxwell equations in vacuum. Direct use for field computation

3. Static field of electric charges. Laplace's and Poisson's eguations

4. Analytic and numeric methods and their use in electrostatics

5. Macroscopic model of materials. Polarisation, magnetisation and its exploration

6. Magnetic field caused by steady currents
