Outline Of Syllabus
Basic vector algebra, definitions of Curl, Div and Grad, review quasi-static fields, Laplace and Poisson equations, continuity equation, derivation of Maxwell’s equations for static and time varying fields. Physical and engineering significance of Maxwell’s equations.
Concepts of distributed circuits, derivation of transmission line parameters, attenuation and phase coefficients, characteristic impedance, Standing Wave Ratio (SWR) definition, lossless and lossy lines and matching techniques.
Derivation of the wave equation, solution of wave equation for the transverse electromagnetic (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.
Design implications of skin effect, corona discharge, shielding, review of Electromagnetic compatibility (EMC) concepts and legislative requirements.
Relevant examples will be provided to reinforce key topics as appropriate.
Teaching Rationale And Relationship
Lectures provide core material and guidance for further reading, problem solving practice is provided through tutorials. Office hours (two per week) provide an opportunity for more direct contact between individual students and the lecturer: a typical student might spend a total of one or two hours over the course of the module, either individually or as part of a group.
Assessment Rationale And Relationship
The examination provides the opportunity for the student to demonstrate their understanding of the lecture course material. The written assignment tests the understanding of the course material through the use of problem solving, testing both mathematical and conceptual understanding.
