Objectives:

On completion of this subject students should:

• understand the behaviour of transmission lines, waveguides, and free space propagation of electromagnetic fields when transmitting and processing high speed signals;

• be able to measure, analyse, and design a variety of electrical transmission networks in the frequency and time domains using combinations of transmission lines, lumped and active networks;

• be able to analyse the behaviour of waves propagating in dielectric waveguides and optical fibres;

• understand the fundamental characteristics of antennas and be able to design simple antennas for free space propagation.
