EE3P11 Electromagnetics

Topics: An introduction to electromagnetic fields and waves

After successful completion of this course, you will be familiar with electromagnetic fields and electromagnetic wave propagation in a variety of settings as encountered in Electrical Engineering and other fields. You will have a thorough understanding of Maxwell's equations and you will be able to explain in your own words how electromagnetic waves propagate through different materials. Moreover, you will know and understand the different kinds of reflection and transmission effects that can take place at the interface between two different media. You will also be able to predict what types of induced phenomena (such as heat production, charge accumulation, and surface current generation) can take place within a piece of matter or at its boundaries. In addition, you will have an understanding of how the electromagnetic field can be used to transport energy (information) from one point to another and you will recognize that so-called transmission lines can be used to guide this energy transport. Finally, you will know how the voltages and currents along transmission lines are related to the electromagnetic field quantities and you will have a firm knowledge and understanding of the propagation properties of these lines.
