Subject Description

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.

The content includes; plane wave propagation with multiple interfaces and oblique incidence. General lossy transmission line in both time and frequency domains. Applications of distributed circuits. Matching techniques, Smith chart. Scattering parameters. Coupled lines and directional couplers. Striplines and microstrip. Waveguides and cavities. Dielectric waveguides, integrated optics and optical fibres. Radiation and simple antennas. Propagation between antennas.

Assessment

One written examination not exceeding three-hours; practice classes, tests, assignments and project reports, not exceeding 20 pages
