PHY2021 : Principles of Electromagnetism

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 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.

Transmission Lines
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.

Electromagnetic Waves
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.

Engineering Examples
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.

Assessment Rationale And Relationship

The examination provides the opportunity for the student to demonstrate their understanding of the lecture course material. The written assignments (two, equally weighted) test the understanding of the course material through the use of problem solving, testing both mathematical and conceptual understanding.
