Intended learning outcomes

General goals

After the course the student shall from a description of a situation that leads to an electromagnetic field problem be able to

• use their conceptual understanding of the electromagnetic laws in order to qualitatively describe the behavior of the solution to the problem

• use their ability to manage the electromagnetic laws to, in simple situations, set up a computational model and perform the necessary calculations: select appropriate methods; make appropriate approximations; asses the plausibility of the results

Concrete goals

1. define electric and magnetic fields according to their force effect

2. explain the physical meanings of the differential equations for electrostatic and magnetostatic fields

3. calculate the electric field from the stationary charge distributions and magnetic fields from steady current distributions

4. solve simple electrostatic boundary value problems

5. describe and use simple models of electric and magnetic field interactions with materials

6. explain the concept of electromotive force

7. write down Maxwell's equations and explain their physical meanings

8. analyze how energy and momentum is stored and transported in an electromagnetic field

9. analyze the propagation, reflection and transmission of plane waves

10. analyze propagation in simple types of transmission lines and waveguides

11. use Maxwell's equations to analyze the electromagnetic fields generated by given dynamic charge/current distributions

12. calculate the radiation fields from simple types of antennas and antenna systems

Course main content

Electrostatics: Coulomb's law. Electric lines of force. Evaluation of electric field and potential in vacuum and with conducting and dielectric materials. Energy and forces in electrostatic systems.
