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.
This aims of this module are to introduce the fundamental aspects of electromagnetic waves in the design and operation of high-speed electronic devices and systems, which include circuit layouts, interconnections, antennas as well as regulatory aspects designed to ensure that devices and systems do not radiate interference.
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.
Outline Syllabus
1. Vector calculus operators and their interpretation in relation to Maxwell's equations.
2. Review of capacitance and inductance and the concept of storage of electric and magnetic field energy.
3. Maxwell equations and free-space electromagnetic waves. Polarization. Waves in media. Metallic conductors and skin depth.
4. Basic transmission lines and waveguides: coaxial, twin-wire, metallic and optical waveguides, and their electromagnetic properties
5. Telegraphy equations, and analysis of transmission lines as the limit of discrete ladder networks.
6. Waves on transmission lines. Characteristic impedance. Standing waves and their relation to impedance termination and matching criteria. Basic modes in rectangular waveguides.
7. Radiation and antennas. Radiation from a short dipole. Radiation from a slot. Reciprocity. Antenna gain and basic link calculations.
8. Electromagnetic compatibility. Unintended radiation. Balancing and shielding of currents. Isolation of power lines.

Exam format definitions
- Remote, open book: Your exam will take place remotely via an online learning platform. You may refer to any physical or electronic materials during the exam.
- In-person, open book: Your exam will take place on campus under invigilation. You may refer to any physical materials such as paper study notes or a textbook during the exam. Electronic devices may not be used in the exam.
- In-person, open book (restricted): The exam will take place on campus under invigilation. You may refer only to specific physical materials such as a named textbook during the exam. Permitted materials will be specified by your department. Electronic devices may not be used in the exam.
- In-person, closed book: The exam will take place on campus under invigilation. You may not refer to any physical materials or electronic devices during the exam. There may be times when a paper dictionary,
for example, may be permitted in an otherwise closed book exam. Any exceptions will be specified by your department.
Your department will provide further guidance before your exams.

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.
