This class is different than most others you have taken in that we take more of a system approach to emc. Thus, there will be less emphasis on exercises and more on general requirements and practices. Because of this, homework assigned will consist of a few assignments on a particular topic. You will be assigned a subject, given approximately two weeks to research it, write a report and present it to the class. There will be 3-4 assignments during the Semester. Your grade will be based on these reports and your presentation. The reports you write will be distributed to the class for future reference.
The reason for this approach is the subject itself. EMC is an elusive subject and, more often than not, is a blend of art and science. Because of this, your conclusions on a particular subject (in class or in the workplace) will almost never going to be clear-cut. Thus the need to present, reason, and defend your findings and opinions.
The first assignment will deal with regulatory issues. The second will deal with specific applications and practices in EMC. The third will deal with emc methods (tests, mitigation, etc.). I will insist that your work and reports be complete, well documented and original work. I want to read and hear your words not those of an internet article.
A word of warning: Because EMC is often poorly understood, you will find, in the course of your searches, many references to nonscientific issues. Be careful, especially when using material off the web. Sometimes you will have to sift through material and discard outrageous claims (you will meet UFO type of claims, world domination type, conspiracy claims, plain nonsense, and many others). Remember that although EMC is a complicated issue, it is purely physical and very real. Beliefs, paranormal experiences and unsubstantiated claims are not part of the science.
