DESCRIPTION - summary of the module content

Malaria testing has come a long way, with the advent of new technology, using electronics rather than blood samples to measure malaria's magnetic movement in the blood. This module brings such groundbreaking developments to life, with Exeter staff at the forefront of these advancements delivering the lectures.

 

The above example shows you one way in which electromagnetics can be applied usefully in the real world. A fundamental knowledge of electomagnetics is critical when pursuing a career in electrical engineering - if, for instance, you are designing an antenna. Beginning with the physical exploration of electromagnetics over approximately the last 200 years, you will study the origins of electric and magnetic fields, looking at the historical impact and application of electromagnetism. Furthermore, you will investigate electrostatics and the electric field as well as magnetic forces and magnetostatics, applying this knowledge to real world engineering problems; exploring theories, such as Maxwell's equations, you will develop essential problem-solving tools.


Meanwhile, studying communication systems, you will consider elements such as the transmission of mobile phone signals and how radio works, incorporating Hertz's first measurement of radio waves. Case studies will challenge you to examine electrical disturbances travelling in transmission lines and the aspects of antenna design by looking at electricity lines to design and measure, for example, what kind of strength and thickness is needed.

AIMS - intentions of the module

The aim of this module is to introduce you to the fundamental principles of electromagnetics, and to teach you how to apply theory to areas of technological importance, including field computation and communication systems. At the end of this module, you will understand the basic principles of electromagnetics, and have a solid foundation in tackling most electronic engineering problems.

 

This module covers Specific Learning Outcomes in Engineering, which apply to accredited programmes at Bachelors/MEng/Masters level. These contribute to the  educational requirements for CEng registration (as defined under the UK Standard for Professional Engineering Competence – UK-SPEC).


This module correlates to references U1, E1 - E3, P1, MU1 - MU3, ME1 - ME3, MP1 and MP2. These references are indices of the specific learning outcomes expected of Bachelors/MEng/Masters candidates set out in UK-SPEC, codified with reference to systems used by professional accrediting institutions. A full list of the standards can be found on the Engineering Council's website, at http://www.engc.org.uk

INTENDED LEARNING OUTCOMES (ILOs) (see assessment section below for how ILOs will be assessed)

RE-ASSESSMENT NOTES

If a module is normally assessed entirely by coursework, all referred/deferred assessments will normally be by assignment.



If a module is normally assessed by examination or examination plus coursework, referred and deferred assessment will normally be by examination. For referrals, only the examination will count, a mark of 40% being awarded if the examination is passed. For deferrals, candidates will be awarded the higher of the deferred examination mark or the deferred examination mark combined with the original coursework mark.
