Prerequisites / Co-requisites
The module reprises electrostatics (Gauss’ Law) and proceeds to introduce electromagnetic theory through a development of Maxwell’s Equations.
The module introduces concepts associated with the electric and magnetic polarization of materials.
It introduces electromagnetic wave theory and its applications to a range of traditional applications and problems as well as the use of Fourier processing for wave signal analysis.
The module aims to present a comprehensive coverage of electromagnetism, electromagnetic waves and the electromagnetic properties of materials. It does this through the development of relevant electromagnetism theory in lectures and though the presentation of traditional applications and problems in lectures and tutorial problems. The module aims to provide further practice in the use of the mathematical tools of vector calculus and partial differential equations learnt in PHY2064.

Electromagnetic Induction, Faraday’s Law (third Maxwell equation), Mutual and self inductance, Energy storage in B-field, Magnetic torque, Magnetic dipoles..
Diamagnets, Paramagnets, Ferromagnetics, Magnetisation M, Magnetic intensity H, Magnetic permeability, Magnetic susceptibility,
Magnetisation current, Magnetic circuits, Reluctance, Hysteresis, Permanent magnets, Boundary conditions for B and H,
Displacement current, fourth Maxwell equation, review of vector analysis,
Electromagnetic Waves and Applications:
The module investigates further the topics of magnetism and electromagnetic waves.
The lectures will go on to combine Maxwell’s equations to investigate electromagnetic wave propagation in vacuum, in materials and the behavior of electromagnetic waves at interfaces:
Electromagnetic Waves, Speed, Refractive index, Attenuation, Skin depth, Uniform Plane waves, Linear Polarisation, Energy density and Power of Waves, Waves at Boundaries - reflection & refraction.
Fresnel's equations, Brewster angle, Total Internal reflection. Transmission Lines
Processing signals images using Fourier analysis and manipulation of Fourier-transformed data.
Methods of Teaching / Learning
33 hours of lectures and 11 hours of class tutorials.
Total student workload is 150hrs, with the remaining hours consisting of independent study
The class test comprises an on-line multiple choice question paper of 20 questions.
The final examination is of 1.5h duration, with 2 questions to be attempted from 3.
The assessment strategy is designed to provide students with the opportunity to demonstrate subject knowledge and ability to apply subject knowledge to unseen problems in electromagnetism, electromagnetic waves and electromagnetic properties of materials.
Thus, the summative assessment for this module consists of:
a final examination of 1.5h duration, with 2 questions to be attempted from 3.
a mid-semester multiple-choice class test.
Problem sets on electromagnetism and electromagnetic waves are provided weekly together with model answers to these questions, which allow the students to test their understanding of course material.
Formative assessment is also provided through weekly online multiple-choice quizzes for the material taught during the second half of the module.
Verbal feedback covering lecture material and problem sets is provided at hour-long weekly tutorial sessions throughout the semester. Model solutions for the questions on the problem sets provide students with feedback on their problem-solving ability. The online multiple-choice quizzes provide model solutions for the questions answered incorrectly.
