Aim of Course: | |
To introduce electromagnetics waves and their properties. This a theoretical course where the principles of modern communicationns lies. It is critical to understand antennas, communications systems and microwave technologies. The course will take you from the laws of physics valid in electro-statics and magneto-statics to the maxwell equations generalising the previous laws for accelarating charges. We will also move from a integral form (global) of these laws to their differential (local) form. Altough this course is quite mathematical, you will have a glimpse at theoretical physics and this can be very rewarding. In any case, do not panic, generations of students have survived it and many actually did enjoy it. |

You will find here some electronics copies of the lecture notes. These copies will not always be available and in any case only after the lectures.
A few paper copies will also be available in 1.56.
These tutorials are year 2001 tutorials. The tutorials are available in pdf format. When you select one of these documents Adobe Acrobat Reader will start and open the document. You will then be able to read it, search it for key words or phrases or print it. When you are finished using the document, go to Acrobat's [File] menu and choose Exit.
Solutions will be made available during the tutorials.
Matlab is a very powerful scientific programming package with outstanding visualisation capabilities. As we progress through the tutorial and the course, you should become more comfortable with Matlab and use it to understand and visualise the physical processes. You will find a small libraries of functions that you can download and use freely. You are encouraged to do so as early as possible. Some functions of the “library” are useful to understand vector calculus and differential forms of the Maxwell equations as wee as the Nabla operator that you will study during the next 3 weeks. Matlab can be used in Lab 2.52 on PC Caledonia where 50 licenses are available. Log in onto your PC Caledonia account and click on the Matlab icone in your desktop. If for some reason, the icone is not there, use the Start Program menu to start Matlab. Then in Matlab, use the cd command to move to the directory where the program lies and type the name of the file to start the program. You will find here a series of short Matlab Programs that you are encouraged to download and try. They are various visual illustrations of the notions (vector calculus, fields, wave) that you are currently studying. They should help you in apprehending the physical concepts and visualising them as well as getting used to matlab.
Matlab online help and tutorials can be found here.
A local copy of Matlab Getting Started manual in pdf format can be found here.
Details of the assignment for this course are now available. The assignment is available on-line in pdf format. When you select one of these documents Adobe Acrobat Reader will start and open the document. You will then be able to read it, search it for key words or phrases or print it. When you are finished using the document, go to Acrobat's [File] menu and choose Exit.
