Key module for

BENGH610DA Electronic Engineering

Module description

Many modern electronic devices are high speed and are widely used in computer, communication, radar and various other electronic systems. The speed of these devices and systems using them can be so high that it is impossible to ignore the fundamental aspects of electromagnetic waves in their design and operation, which include circuit layouts, interconnections, antennas as well as regulatory aspects designed to ensure that devices and systems do not radiate interference. After introducing the basics of vector calculus and laws of electromagnetic fields and waves, the module converges toward the treatment of transmission lines and waveguides, matching, and mechanisms by which structures can radiate either intentionally or unintentionally.

Module aims

This aims of this module are to introduce the fundamental aspects of electromagnetic waves in their design and operation, which include circuit layouts, interconnections, antennas as well as regulatory aspects designed to ensure that devices and systems do not radiate interference.

Module learning outcomes

On completion of the module, students will be able to:

1. understand basics of vector calculus and their applications to electromagnetics fields and waves ;
2. explain basic electromagnetic laws in words and mathematical forms
3. evaluate electromagnetic properties of basic transmission lines and waveguides;
4. solve simple problems relating to transmission line matching and standing waves;
5. describe radiating waves in free-space and other media;
6. explain properties of a basic antenna in transmission and reception;
7. evaluate qualitatively techniques for achieving electromagnetic compatibility.

Exceptionally it can be necessary to make changes, for example to programmes, modules, facilities or fees. Examples of such reasons might include a change of law or regulatory requirements, industrial action, lack of demand, departure of key personnel, change in government policy, or withdrawal/reduction of funding. Changes to modules may for example consist of variations to the content and method of delivery or assessment of modules and other services, to discontinue modules and other services and to merge or combine modules. The University will endeavour to keep such changes to a minimum, and will also keep students informed appropriately by updating our programme specifications and module directory.
