Venue: Embassy Suites in Livonia
EMC design is one of those subjects mired in tradition and often is impaired by design rules that do not quite apply to the situation at hand. Alternatively there are very sophisticated tools using Computational Electromagnetic (CEM) techniques that are capable of solving complex problems with great precision – providing the user knows how to apply them appropriately.
Many EMC engineers were trained to trust a wide range of rules and measurements, and developed excellent hands on debug skills. At the other extreme, others tried to develop entire designs using only computational approaches. The reality is that for most new product designs, the use of a combination of tools is needed to most efficiently proceed.
This series of talks will explore the strengths and weaknesses of many tools, including traditional rules, common design guidelines, analytic techniques, and computational modeling. Each will be examined to see not only how it can be best applied but also what the designer needs to know to properly apply the tool. The goal is to better prepare the EMC design engineer to address new design work confidently and without doubt regarding the tools used.
Shielding performance is one area where there are well understood equations that can be applied to accurately determine performance. Along with the basic physics there are a number of corrections that help the idealized case to be more accurately applied to a more complex situation. Beyond that are some rules of thumb that help apply the approach to practical enclosures. However, there are cases where the shielding performance problem no longer meets the assumptions required for the use of the equations and the associated modifications; then erroneous results are obtained.
One area of study that is available to designers are validation methodologies that can help a user by providing an increased degree of confidence in the design data, be it derived from a computer model or a measurement. While this is not a commonly used approach, validation tools, even as a means of check and balance, can help to ensure that a design is kept on the right track; this is a powerful design aid. An example will be presented on the use of a validation tool during a new product design and the significant impact that was had on the final product design.
Computational tools have grown in sophistication. This has occurred not only with the increase of computer power available and the application of newer solution methods, but also with coding that addresses many typical or expected situations by biasing the model in a certain way. This later development can greatly speed the run time for a problem but can be problematic for the EMC engineer. For example, a code developed for antenna design can safely make assumptions that the antenna will be deployed in a position where it can freely radiate. If such a tool is used for an EMC task where the antenna does not conform to the expected parameters, then serious errors may result, quite possibly without the user being aware of the issue. Again, examples from actual product development work will be provided to highlight how to avoid such pitfalls.
Due to the complexity of most products, one tool or design approach is seldom adequate. This means that it is often necessary to find a way to break a design problem into multiple smaller parts that can each be examined separately. It is necessary to do this in such a way that the smaller parts can be later re-combined to complete the design. Often, partitioning a problem in this manner not only makes the task easier but can also provide some additional understanding of the problem.
A powerful resource that must always be used is the existing, experienced-based knowledge of the designer him/herself. However, this too can be misapplied. Depending upon the level of experience, personality and the rush to get the design done correctly, it is possible to lose a balanced approach. The designer might ignore common sense provided by experience and so trust a technique without question, or he might avoid the use of such a tool and go with experience alone. The key to success is understanding the strengths and limitation of all resources, including yourself.
While this class (series of talks…) will provide many insights regarding the use of design tools, the most important lesson is to provide the attendee with a way of thinking through a design to minimize surprises that can so easily occur. Ensuring a balanced approach to EMC design, using a combination of the designers’ experience, measurements, analysis and computational models, can make the resulting EMC design work much less uncertain. EMC design is really not just black magic – it is the combination of a good number of dark grey magic steps.!

Colin E. Brench (M’80-SM’04) is currently a Principal Engineer at Amphenol High Speed Interconnects, in Nashua, New Hampshire, where he is responsible for the EMC aspects of high data rate (10 to 56 Gbps) interconnect schemes.
He received his B.Sc. (Hons) in Electronic Engineering at The City University, London, in 1975, and has been particularly active in the areas of EMC, antennas, and shielding behavior since the early 1970’s. Colin has presented numerous EMC workshops and training classes that embrace a broad range of topics including microprocessor packaging, printed circuit module issues, system design, and shielding. He is a co-author of the book, EMI/EMC Computational Modeling Handbook (Springer, 2nd Edition 2001), has authored over 20 technical papers and articles, and holds 12 patents for various methods of EMI control.
Colin is a Senior Member of the IEEE, member of the EMC Society since 1980, and an iNARTE certified EMC Master Design Engineer. He was appointed a Distinguished Lecturer for the IEEE EMC Society for 2001 and 2002, and has given several seminars for various IEEE chapters and sections. In 2002 he was awarded the Certificate of Technical Achievement by the IEEE EMC Society for his contributions to the development of EMC modeling directed to understanding EMI shielding and antenna behavior.
Colin has also been active in IEEE EMC-S standards, IEEE EMC-S Technical Committee 9 (TC-9), ANSI ASC63, and served 11 years on the IEEE EMC-S Board of Directors.
