Professor Alan Robert Clark (course co-ordinator)
Electromagnetics pervades almost every aspect of our everyday lives, WiFi, 4G, LTE, Bluetooth, GPS, Microwave Ovens, Radar, Remote Sensing, Medical Electronics, Roving Mars Robots, Pictures of Pluto…
All these interact with one another and with humans, but this is unseen: Hence the need for knowledge in this area to minimise nonsense!
In many ways, Electromagnetics can be viewed as a superset of circuit theory, with the power flow through the mysterious “ether” as opposed to a physical circuit. Thus the student is exposed to a broader and more general context than before.
Electromagnetics lays the foundation for the High Frequency course, where antenna design is important for the eventual implementation of any wireless communication system. Any high-speed (Analogue or Digital) electronic circuit cannot be understood without these techniques.
On successful completion of this course, the student is capable of:
Thorough knowledge of basic physics, especially the field components, and a thorough grasp of mathematics, especially vector calculus.

The examination will cover all material covered in the course, and especially discussion topics in lectures and tutorials.
The student’s understanding of the fundamental aspects of the course will be probed. Exam questions etc will need to be answered in order to answer the question: “WHY?” as opposed to the simplistic “HOW”. I am not attempting to assess a simple methodology, I will assess fundamental understanding of concepts.
Note that the onus is upon the student to convey this understanding in an examination. A terse, correct “answer” may not necessarily attract marks! Please refer to my exam writing skills notes at ytdp.ee.wits.ac.za/ExamWritingSkills.html.
For the purpose of Rule G.13, satisfactory performance in the work of the class means attendance and completion of prescribed laboiratoty activities, attendance at tutorials designated as compulsory in this CB&O, submission of assignments, writing of scheduled tests unless excused in terms of due procedure.
My lecturing style is highly interactive, and largely of the “chalk and talk” variety. This means that the emphasis during lectures is upon understanding, and not on “transferring the lecturer’s notes to those of the student, without passing through the minds of either”. Interaction on the part of the student is required.
One negative consequence of an interactive lecturing style (as opposed to a transfer of notes style), is that the student actually gains an understanding in the lecture. If it assumed that this initial understanding is all that is required, disaster occurs. Learning is an iterative exercise, and requires constant re-inforcement. My lecturing style can thus lead to a complacency which is rudely interrupted at examination time. HENCE:
Tutorial exercises are designed to complement and probe material currently being taught. They are not necessarily designed as examination questions, which typically cover more comprehensive, integrated material. Doing these tutorial exercises only just before the exams will not help. They are to be done concurrently with the material being explored. The past exam papers are to be used as a benchmark for examination questions.
No text perfectly covers the course material: all books have flaws. The Prescribed Text is:
There are no notes handed out for this course.
In addition, there is a 122 page “Study Guide”, by some obscure bloke:
available from the Course Home Page. (See below).
There are some excellent eTexts available, see Course Home Page…
If it can be obtained the Third Edition of “Electromagnetics” by J.D. Kraus (McGraw-Hill) is definitive. The Fourth Edition is OK, the Fifth Edition, co-authored by Fleisch, is completely useless.
There will be three lectures per week. Students are expected to attend all lectures and to make their own notes.
I keep strictly to South African Standard Time (SAST). I respect your time, and will not drag on my lectures, and I expect you to respect my time, and that of your colleagues, by arriving on time, so that latecomer disruption is avoided.
There will also be one tutorial per week.
There is no project associated with this course.
There will be a laboratory associated with this course held in the Basic Laboratory, covering topics taught in the course, as well as topics not formally dealt with in lectures.
Students who have not done the lab preparations will be asked to leave the laboratory.
School Policy states that there are no lab exemptions.
I have what I call a “Modified Open Door” policy. You can come and see me at any time, but only in groups! I have a great regard for the peer-support system; you only really understand something if you can explain it to your peers. I have long ago forgotten the particular difficulties I had with some of the concepts taught in this course, they now appear to me as “obvious”; peers do not have this myopia.
The preferred method of contact, however, is email.
It is generally convenient to grab me between and after lectures.
