6) Transmission lines: Modelling of Short, Medium and Long transmission lines in electrical power distribution systems. Cable charging currents. Transients in Transmission lines, Reflections, Termination.

7) Waveguides: Rectangular waveguides. Transmission modes.

Study-unit Aims:

This study-unit introduces electromagnetic theory and covers the basic concepts behind antennas, waveguides and transmission lines.

Learning Outcomes:

1. Knowledge & Understanding:

By the end of the study-unit the student will be able to:
- Write down the fundamental laws of electromagnetism and be able to argue how it the subject underpins all of Electrical Engineering.
- Explain with conviction all the concepts and interrelationships between static or varying, electric and magnetic fields.
- Explain the underlying meaning of mathematical tools such as integration, differentiation, curl, grad and div through physical phenomena like electromagnetics.
- Explain how such mathematical skills are directly transferable to fluid mechanic analogies such as vortices, incompressible steady flow, stokes law, force fields etc...

2. Skills:

By the end of the study-unit the student will be able to:
- Work-out numerical problems in electromagnetics.
- Apply classical and vector calculus to solve 3-dimentional problems in electrostatics and magnetostatics.
- Mathematically model simple antennae, waveguides and transmission lines.
