Though the concept of using a TDR to measure permittivity is not new, it has not become widely known and accepted. It will be shown that reasonable results can be obtained with this method and that the values obtained for relative permittivity can be used with excellent results when used in the proper closed form equations or modeling method. This method is particularly useful when processes, as in present day laminated circuit boards, have had an impact on the effective permittivity. In these cases using published values or using conventional methods for determining permittivity can lead to errors in computations for characteristic impedance.","PeriodicalId":93568,"journal":{"name":"IEEE International Symposium on Electromagnetic Compatibility : [proceedings].

It is also aimed at working engineers who encounter practical EMC problems, which they describe in the course and provide motivation and realism to the course content. The lecture segment of the course covers the essential topics, and is followed by a series of student project seminars. Contact with modern measurement requirements and instrumentation is provided with demonstrations and site visits. Historical Background Educational programs in Electromagnetic Compatibility tend to have special characteristics, which are best understood in the light of their historical development and the local demands and resources which shape objectives and content. Concordia University was created in 1974 from the amalgamation of Loyola College and Sir George Williams University. At the time of amalgamation, the authors were involved in the development of an undergraduate electrical engineering curriculum at Loyola which had strong links to the local industrial community and in an initial research program for the development of EMC prediction techniques [ 11 for avionics systems. After amalgamation, the research activity was extended to the application of computational electromagnetics to the modelling of radiation and coupling problems for complex structures and special problems such as the interaction of broadcast antennas and power lines [2] and specific aerospace projects [3]. The scope of this activity and the size of the research team became sufficient for the EMC Laboratory lo be recognized as such. At the same time the graduate program in electromagnetics was strengthened to provide a coherent set of relevant courses for graduate students. During 1985 an opportunity presented itself for the extended visit of Dr. Andrew Marvin of York University to Concordia, and it was most opportune to exploit his experience and expertise for the organization of the first EMC course [4] in Quebec. This course has evolved somewhat since, but continues to be offered on a yearly basis and provides, together with the EMC-related research activity, a focal point for EMC graduate interest. Its present content and emphasis is best understood from the perspective of the graduate program requirements at Concordia.","PeriodicalId":93568,"journal":{"name":"IEEE International Symposium on Electromagnetic Compatibility : [proceedings].

Weiner","doi":"10.1109/ISEMC.1992.626070","DOIUrl":"https://doi.org/10.1109/ISEMC.1992.626070","url":null,"abstract":"ELECTROMAGNETIC COMPATIBILITY is proposed as a new 500-level course in Electrical Engineering. This course will augment the relatively few design courses available to students in Electrical and Computer Engineering. It will also satisfy the need by industry for students who understand problems associated with designing electromagnetically compatible products. To enhance the design aspect of the course, demonstrations and experiments will be included. A) PROBLEM STATEMENT The accreditation board for Electrical and Computer Engineering undergraduate programs requires that undergraduate students take a minimum of 16 design credits. Currently, Electrical and Computer Engineering students at Syracuse University have little flexibility in selection of their design courses. To alleviate this situation, it is proposed to develop a new 500-level design course to be taught for senior and first-year graduate students. In selecting the topic area for such a course, consideration was given to industrial requirements. Manufacturers of electrical products and electronic systems are keenly aware of the importance of electromagnetic compatibility (EMC). For example, it is important that the electromagnetic radiation from a home computer not interfere with television reception. As a rule, industry cannot afford an in house program to train their beginning engineers to the necessary level of EMC design competence. Consequently, industry today considers a basic knowledge of EMC to be as important a part of an Electrical or Computer Engineer’s education as is circuits, digital design, signal theory, electromagnetics, etc. Nevertheless, according to a survey in 1985 by the Education Committee of the IEEE Electromagnetic Compatibility Society, only a few colleges and universities offer courses dealing with EMC. In spite of this, most respondents felt that there was a need to include this material in the Electrical Engineering curriculum. To satisfy this need, ELECTROMAGNETIC COMPATIBILITY was selected as the subject matter for the new design course. B) OBJECTIVES The course material will be based on the text, INTRODUCTION TO ELECTROMAGNETIC COMPATIBILITY, by C.R. Paul. The manuscript has only recently been accepted for publication by John Wiley and Sons, Inc. (I served as one of the reviewers for John Wiley.) A course outline, based on this text, is included with the supporting documents. In a design course of this nature, it is important that the student observe demonstrations and have an opportunity to conduct experiments. Not only will this help the student to understand and retain the course material, it will also provide the student with an opportunity to see and use modern measurement equipments and to CH3169-0/92/0000-0032 $3.00 01992 IEEE 166 obtain an appreciation for realistic \"numbers\" to be observed in practice.
