Synopsis

In this module you will be provided with greater understanding of electric and magnetic forces and fields and their unification in Maxwell’s equations. You will be able to carry out vector analysis and the mathematical descriptions of the fields, an examination of the basic laws governing the generation of fields, and a study of interactions with dielectric and magnetic materials. Electromagnetic propagation is fundamental to communications and after this module you will be familiar with both transmission line and free-space propagation. You will also cover reactive circuits and their transfer functions, frequency and phase response, Bode equations and their plots.

Learning Strategy

In this module the learners will engage in a blend of delivery methods facilitating both individual and collaborative aspects of learning to achieve the specified learning outcomes. In particular, this will require the learner to engage with the VLE content, including extensive pre-recorded teaching and support materials, where the learning is facilitated by the tutor-led two-way asynchronous discussion board. To focus the guided learning process, the tutor will set weekly quizzes/assignments (SAIL). These two elements will culminate in face-to-face sessions which will reinforce the learning by clarifying the content through student-led questions/answers interaction. These sessions are followed up by tutorials to illustrate the module content and enable practice in more depth. Where possible cohort scale groups will be used in face to face sessions offering the benefit of a full range of student input and engagement. Within this module, students will have an opportunity to work as part of a professional engineering team of peers to address an authentic multi-disciplinary short group project (part of EnABLE programme). EnABLE group challenges operate over 5 weeks, in which groups of 8-10 students will work together on a specific engineering problem. They will be guided and facilitated in regular mixed sessions to achieve and finally present their own unique solutions. Students with disability will be accommodated by close adherence to the University of Huddersfield guidelines which inter alia include: (i) pre-recorded materials with captions of suitable size, (ii) Power Point slides following the appropriate font size and colour contrast, (iii) early availability of all materials on VLE – typically at least two weeks in advance.
