EEE2015 : Electromagnetic Fields & Waves

Semesters
Semester 2 Credit Value: 10
ECTS Credits: 5.0

Aims

To enhance the students' knowledge of electromagnetic fields and wave behaviour and how this can be used to describe quasistatic fields, transmission lines and plane waves.

Outline Of Syllabus

Maxwell Equations
Basic vector algebra, definitions of Curl, Div and Grad, review quasistatic fields, Laplace and Poisson equations, continuity equation, derivation of Maxwell’s equations for static and time varying fields. Examples of static and time varying fields, applications of Laplace, Poisson and continuity equations, the physical significance and engineering relevance of Maxwell’s equations.

Transmission Lines
Concepts of distributed circuits, derivation of transmission line parameters, attenuation and phase coefficients, characteristic impedance, SWR definition, lossless and lossy lines and matching techniques. Examples in engineering practise, measurement and matching techniques.

Electromagnetic Waves
Derivation of the wave equation, solution of wave equation for TEM case, plane wave concepts, wavelength, attenuation and phase constants, propagation of waves in lossless and lossy media, polarisation, wave power (Poynting vector), interaction with dielectric and conducting media, and wave reflection and refraction. Examples in wave propagation, power flow in polarised fields and wave reflection and refraction.

Engineering Examples
Design implications of skin effect, corona discharge, shielding, review of EMC concepts and legislative requirements.

Assessment Rationale And Relationship

The examination provides the opportunity for the student to demonstrate their understanding of the lecture course material.

The Practical Lab Report 2 provides students with an opportunity to demonstrate an understanding of practical lab measurements on electromagnetic devices and their interpretation.

The emphasis and content of Report 1 essay required is very flexible so that students can select areas of concentration in electromagnetics that they personally find interesting.
