Development of Japanese EMC Engineering in 1996-2009 and Prospects

Abstract

SUMMARYSubjects in Electromagnetic Compatibility (EMC) research that have been presented at meetings of the IEICE Technical Committee on Electromagnetic Compatibility (EMCJ) are overviewed and categorized. The temporal changes in the proportions of the categorized subjects among the total number of presentations each year is also shown. Finally, speculative opinions are presented on what EMC subjects will be studied in the near future. key words: IEICE, EMCJ, subjects, review, prospects IntroductionIn Japan, subjects related to electromagnetic compatibility (EMC) have been covered at technical meetings of the Technical Committee on Electromagnetic Compatibility (EMCJ). The EMCJ was founded in 1977 as a part of the Institute of Electronics, Information and Communication Engineers (IEICE). Meetings have been held almost monthly, along with a few special events such as a tutorial workshop and another meeting, called the "Yuzawa Workshop," that deals with the hottest current subjects at that time of the year.EMC research subjects arose immediately after the start of electric communication. Over the next century, bandwidth expanded beyond 100 GHz, while the range of communication extended to a few million kilometers, reaching Mars. The amount of information exchanged over the globe is seemingly limitless, and the speed of personal communication often exceeds 100 Mbits/s. Under these circumstances, EMC subjects has expanded their coverage from radio communication to electrostatic discharge (ESD), electromagnetic interference (EMI) from digital devices, the biological effects of radio waves, and even to electromagnetic (EM) theory itself, which has been modified to a form more suitable for the wider range of engineers working in electrical industries. Deeper understanding of EM theory is still being cultivated as new EMC subjects arise during technological development.This report was first written for the annual report of the Kansai Electronic Industry Development Center [1]. It was then revised and submitted to the IEICE transactions of communications (Japanese Edition) [2]. The contents were revised to include newer materials and are presented here in English in order to introduce EMC research activities in Manuscript
