It is a common requirement of an electrical engineer to convey electrical energy from one place to another, whether for the purpose of power or information transport, such as for a power station, a radio transmitter, or even across a digital circuit board. For any appreciable distance a.c. voltages and currents on the line must be regarded as a travelling wave. Through a clear understanding of these wave concepts students will be able to design and diagnose transmission lines or waveguide structures used for power or information transfer and form a foundational understanding of electro-magnetic design. This course follows on from ELE2601, and leads into ELE4606 and ELE4607.

Students will comprehend the nature of electric and magnetic fields associated with voltage and currents and how these may be similarly propagated as a travelling wave where such fields constitute the basis of electrical machines and are the cause of much unwanted interference. Students will gain an understanding of both wave propagation and electro-magnetic fields and their application to a wide range of electrical engineering designs.
