2009 Activity Report of Commission E(Electromagnetic Noise and Interference)
October 29, 2009,

By Ryuji KOGA

Domestic Topics:

EMI control technologies are of the prime interest of engineers who supply high-speed
electronic devices. Those who design electronic apparatuses are always looking for more effective,
versatile method of EMI control. Research activities are held in many farms, but results are apt to beclosed to the farm. EMC researches are held in a few universities out of more than 100 Universities
that have engineering department.
Automobiles as well as electronics are commodities to be exported in order to support Japanesepeople. These days the electric vehicles are expected as a resolution for the global green-house effect,in which radio receivers must work with 30-100kW driving electric system. The EMC problems in
automotives are problems of today and tomorrow in Japan. Thus EMC technologies to suppress
noise are fundamental technologies that assure the existence of the country.
Bioelectromagnetics is the continuing subject that resolves the anxious of the public.

Academic activities:
1.

Commission E had, in the period of April 2009 to September 2009, 3 technical meetings incorporation with the Technical Committee on Electromagnetic Compatibility (EMCJ) of the Instituteof Electronics, Information and Communication Engineers of Japan (IEICE). More than 33 papers
were read there, 20-30 minutes each. All of them were held in Japanese with English abstracts inproceedings. List of the titles are found in a web-page,
http://www.ieice.org/cs/emcj/index.html#abstract.

The 2009 International Symposium on Electromagnetic Compatibility, Kyoto (EMC ’09/Kyoto), was held 20-24 July, 2009, at the Kyoto International Conference Center. TheSymposium has been held every five years since 1974, and this is the 6th since its start.
The symposium was held just after the “Gi’on Festival” in Kyoto, which is one of three famous
festivals in Japan, attracting many visitors from all over the world, not to mention many domestic
visitors. Ordinarily the climate at this time of year is very hot, drawing people away from work andtoward these enjoyable summer festivals. It was, however, rather cool this year, and the heavens
cooperated in welcoming our symposium guests. The Sun and Moon also displayed an attractive
show?a partial solar eclipse?right in the midst of our symposium.
The venue of this symposium, KICC, was built 40 years ago in order to accommodate

“international level” meetings by the Japanese government as a part of the ministry of foreignaffairs. The scenery around the center is designed according to a traditional Japanese principle,“borrowed scenery”, namely the environmental scenery of nearby mountains and forests appearing
to be part of the garden. Tall buildings are prohibited by law to be in view from the garden. Inside
the conference center visitors would feel as if they are stepping into the “Starship Enterprise,” whilethe outer profile of the building is modeled after ancient 2000-year-old Japanese architecture.
The number of attendees was around 420 from 20 countries and districts. Two hundred andtwelve technical papers were presented in four days, during four parallel sessions. Sessions on
automotive electronics were originally planned, but the global economic recession that arose last
autumn spoiled those plans. Most of the affected companies denied permission for their engineers toeither present papers or attend the symposium, due to traveling costs. Similar situations occurred inother fields, but not to the extent that we saw in the automotive field. It is our great relief to hear thatthe economy is gradually recovering these

3. 2009 Asia-Pacific Conference on Environmental Electromagnetics(CEEM’2009) was held in
September 16-20, Xi’An, China. Attendee from Japan was not so many because Japanese Domestic
Meeting held by IEICE was totally overlapped.
