EMC Standards The EMCS also has a VicePresident of Standards and the EMC Society has developed a number of standards over the years. The EMCS has had an interest in developing standards in the area of EMC almost from its origin as a Society. Current EMC Society standards include approximately 15 standards. International Membership Growth During its first 25 years of growth, the EMC Society was oriented towards the United States. The symposia were called National Symposiums, and most members were from the United States. Of the 21 active EMCS chapters in 1982 when the EMCS was 25 years old, 20 were located in the U.S., and the sole chapter outside the U.S. was located in Tokyo, Japan. Contrast that to the 2008 list of EMCS Chapters. There are 67 EMCS Chapters and 34 of them are outside the U.S. The membership of the EMC Society has also shown international growth. The current composition of its 4000 members is 60% from the U.S. and 40% from outside the U.S. Future The EMC Society has a history of high-quality EMC Transactions, comprehensive and educational International EMC Symposiums, excellent EMC Standards, and outstanding Technical Committees. Even as the Society looks back in satisfaction at its 50th Anniversary celebration, it is also preparing for another 50 years of progress in its unique niche of electrical engineering. communicate with our portable electronic devices. Laptops have multiple radios in them for communications, but the radio signals and circuitry sometimes interfere with the operating circuits of the host laptop, giving a whole-new perspective to the age-old term “radio frequency interference!” Conclusion The EMC Society has grown from a few hundred members in 1957 to its current size of over 4000 members. The number of chapters has grown to match the growth in membership. The Society now includes members and chapters from all over the world. The EMC Society has a history of high-quality EMC Transactions, comprehensive and educational International EMC Symposiums, excellent EMC Standards, and outstanding Technical Committees. Even as the Society looks back in satisfaction at its 50th Anniversary celebration, it is also preparing for another 50 years of progress in its unique niche of electrical engineering. Daniel D.

As technology is constantly changing, so too has EMC technology changed to address the new issues that arise. Faster clock rates and smaller chips, coupled with a continually declining cost of computer memory, are driving products to be smaller and yet more portable and powerful. This includes computers, hand-held communications devices, including cell phones and personal data assistants, mobile GPS systems for cars and other similar transportation devices, digital cameras, and medical devices. Both emission and immunity issues will continue in the future with the development of these technologies. Fiber optics and fiber optic computers may arrive in a wave of innovation. However, there will be a fiber optic/electronic interface for many years to come which will have EMC aspects to it. Spectrum allocation issues are multiplying as rapidly as wireless devices (cell phones and similar hand-held wireless electronic units) are proliferating. We want access to signals, yet we don’t want to be interfered with when we attempt to 20 Conformity AUGUSt 2008 2. 3. FAST Link www.conformity.com/2030 http://www.conformity.com/2030
