This module introduces students to microwave and optoelectronic technologies. It covers the key features of modern microwave wireless systems, their operations and design requirements. Also covered are basic concepts of optoelectronics. Students are shown how various optoelectronic devices are currently used in laser line-of-sight and fibre optic communication systems. The module develops analytical and design knowledge and provides experience of team working through group work.

Balance of independent study and scheduled teaching activity
Students will be expected to carry out independent background study to familiarise themselves with the platforms and tools that will be used during the module. The module includes online learning material via Weblearn (VLE), face-to-face delivery of content, teaching/tutorial and assessment activities, student support and feedback.
LO1 Demonstrate knowledge and understanding of key features/characteristics and applications of modern microwave & fibre-optic systems, their operations and design requirements including the key components constituting these systems;
LO2 Evaluate components of microwave & fibre-optic systems in terms of quality and trade-offs using analytical tools and modelling techniques with due consideration to system specifications and other relevant factors in the planning and design of such systems;
LO3 Explain the operating principles of a typical microwave & fibre-optic communications link;
LO4 Discuss through design and analysis the key factors affecting the performance of a typical microwave and fibre-optic systems;
LO5 Apply appropriate concepts and principles of microwave and fibre-optic communications to analyse and critically evaluate the performance of such systems individually as well as being an effective member of a team.
The theoretical components of this module are delivered through a series of lectures supported by problem classes, tutorials, directed independent learning, and e-learning/blended learning to promote learning outcomes LO1-LO4. The practical aspects are covered in a laboratory programme, where students are required to design, optimise and critically analyse the performance of microwave and fibre-optic systems to promote learning outcome LO5. Students work in small groups, maintain a record of their work in a logbook and use this to produce an individual technical report based on their practical work. All supporting material on the module (lectures/ tutorials/ assignments/ recordings) is available to students on Weblearn (VLE). This site is continuously updated with guidelines and additional lecture support material throughout the year. Rapid feedback will be provided within two weeks of submission of coursework so that students can gauge their knowledge and understanding. The module is concluded with a closed-book end of module 2-hour unseen examination (summative assessment), which is used to assess LO1-LO4.
