Unit Information

This unit is concerned with propagation, including the behaviour of transmission lines and the theory of electromagnetic waves based on Maxwell's equations.

Elements:

Revision of vector calculus: the gradient, divergence and curl of static electromagnetic field quantites.

Maxwell's equations in time-varying (and time-harmonic) cases; plane waves in lossy and lossless infinite media; wave impedance, skin-depth and power flow.

Transmission line characteristic impedance and the four component equivalent circuit; standing waves, impedance matching and determination of transmission line parameters from simple measurements.

The characteristics of antennas as intentional receivers and transmitters of electromagnetics waves, and brief consideration of unintentional reception and transmission of such waves (an aspect of EMC).

Laboratory:

RF Subsystem Design

Your learning on this unit

On completion of this unit, students will be able to:

  1. Explain Maxwell's equations in both time and frequency domain form
  2. Describe the properties of plane waves in lossy media and the behaviour of voltages and currents on unmatched transmission lines.
  3. Calculate quantities such as wave impedance, skin depth, input impedance and VSWR

How you will learn

Teaching will be delivered through a combination of synchronous and asynchronous sessions, including lectures, practical activities supported by drop-in sessions, problem sheets and self-directed exercises.

How you will be assessed

Formative: Lab Assessment & Online Test

Summative: Exam (Summer, 100%)

Resources

If this unit has a Resource List, you will normally find a link to it in the Blackboard area for the unit. Sometimes there will be a separate link for each weekly topic.

If you are unable to access a list through Blackboard, you can also find it via the Resource Lists homepage. Search for the list by the unit name or code (e.g. EENG25000).

How much time the unit requires
Each credit equates to 10 hours of total student input. For example a 20 credit unit will take you 200 hours of study to complete. Your total learning time is made up of contact time, directed learning tasks, independent learning and assessment activity.

See the Faculty workload statement relating to this unit for more information.

Assessment
The Board of Examiners will consider all cases where students have failed or not completed the assessments required for credit. The Board considers each student's outcomes across all the units which contribute to each year's programme of study. If you have self-certificated your absence from an assessment, you will normally be required to complete it the next time it runs (this is usually in the next assessment period).
The Board of Examiners will take into account any extenuating circumstances and operates within the Regulations and Code of Practice for Taught Programmes.
