2.1 Course summary
Electromagnetism is important from both fundamental and applied viewpoints. This course aims to
provide students with an introduction to the principles and behaviours of electric and magnetic
systems, and the unified subject of electromagnetism in terms of Maxwell’s four equations. Building
on electromagnetic theory, we will analyse a number of problems that are of importance in optical and
radiofrequency engineering.

Topics to be covered include:
? Electric field and force due to a static electric charge distribution.
? Electric potential.
? Work and energy.
? Laplace’s equation and solution methods.
? Electric polarisation.
? Linear dielectrics.
? Lorentz force.
? Magnetic fields due to a steady current distribution.
? Magnetic vector potential.
? Magnetization.
? Linear media.
? Time-dependent fields.
? Faraday’s law.
? Inductance.
3
? Maxwell’s equations.
? Electromagnetic waves in vacuum.
? Electromagnetic waves in linear dielectric media.
? Fresnel reflection at dielectric and metallic interfaces.
? Electromagnetic waveguide modes.
? Thin film optics.
? Polarisation states.

2.4 Relationship between course and program learning outcomes
and assessments
Course learning outcomes 1-3 are assessed in the 4 assessment tasks. These assessments are
largely of a critical-thinking nature designed to determine students’ ability to deploy acquired
knowledge to new situations, which is a key graduate attribute for successful university graduates.

3.2 Expectations of students
We believe that effective learning is best supported by a climate of enquiry, in which students are
actively engaged in the learning process. To ensure effective learning, students should participate in
class. Effective learning is achieved when students attend all classes, have prepared effectively for
classes by reading through previous lecture notes, in the case of lectures, and, in the case of tutorials
or laboratories, have made a serious attempt at doing the problems or pre-work themselves prior to
the class. Furthermore, lectures should be viewed by the student as an opportunity to learn, rather
than just copy down lecture notes. Effective learning is achieved when students have a genuine
interest in the subject and make a serious effort to master the basic material. Academic misconduct
will not be tolerated in any form in this course. Substantiated instances of cheating, plagiarism or
copying answers may result in a failure grade or significant deduction of marks. Please see

http://student.unsw.edu.au/plagiarism if you are in any way unsure of what constitutes plagiarism.
Assignments in this class are to be done independently.

6. Academic integrity, referencing and plagiarism
Referencing is a way of acknowledging the sources of information that you use to research your
assignments. You need to provide a reference whenever you draw on someone else's words, ideas or
research. Not referencing other people's work can constitute plagiarism.
Further information about referencing styles can be located at student.unsw.edu.au/referencing
Academic integrity is fundamental to success at university. Academic integrity can be defined as a
commitment to six fundamental values in academic pursuits: honesty, trust, fairness, respect,
7
responsibility and courage.1 At UNSW, this means that your work must be your own, and others’
ideas should be appropriately acknowledged. If you don’t follow these rules, plagiarism may be
detected in your work.
Further information about academic integrity and plagiarism can be located at:
? The Current Students site student.unsw.edu.au/plagiarism, and
? The ELISE training site subjectguides.library.unsw.edu.au/elise
The Conduct and Integrity Unit provides further resources to assist you to understand your conduct
obligations as a student: student.unsw.edu.au/conduct.
