2008 Activity Report of Commission E(Electromagnetic Noise and Interference)
Domestic Topics:
The power line communication system (PLC) has been brought into commercial application
after critical controversies for three years between venders of terminals, and other victim-sides, e.g.
radio amateur or radio astronomers. In Japan, aerial lines are used as feeder line, which supplies
electricity to homes, and radiation from it is seriously worried.

EMI control technologies are still of prime interest of high-speed electronic device supplier.
Engineers who design electronic apparatuses are always more effective, more versatile method ofEMI control. Research activities are held in many farms, but results are apt to be closed to the farm.
EMC researches are held in a few universities out of more than 100 Universities that haveengineering 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.

Academic activities:
1.

Commission E had, in the period of April 2008 to March 2009, 9 technical meetings incorporation with the Technical Committee on Electromagnetic Compatibility (EMCJ) of the Instituteof Electronics, Information and Communication Engineers of Japan (IEICE). More than 100 papers
were read there, 20-30 minutes each. Most of them were held in Japanese with English abstracts inproceedings. A few presentation were made in English, most of them are by foreign students orresearchers. List of the titles are found in a web-page,
http://www.ieice.org/cs/emcj/index.html#abstract.

2.

A small sized international meeting, Pan-Pacific EMC Meeting (PPEMC) has been regularly
held till the year of 2006.

Third event was held May 15-16, 2008 at NTT Musashino

R&D Center, Tokyo.
3. “2008 Electrical Design of Advanced Packaging and Systems, EDAPS 2008” was held in 10-12,
Dec, 2008, Seoul, Korea. This is mainly related with LSI packaging but many EMC subjects areincluded.

4. “2008 Asia-Pacific Symposium on Electromagnetic Compatibility” was held in conjunction withthe 19th Intern. Zurich Symposium on Electromagnetic Compatibility, as called “Asia-Pacific EMC
Week in Singapore 2008” May 19 - 22, 2008.” This is independent with the one that is held in Zurich.
Attracting EMC engineers in South-East Asia where electronics industries are emerging recently.

5. Chair of commission E in Japan, Prof. Ryuji Koga attended the URSI Assembly on August 2008,
Chicago, and contributed to the discussion in the Commission-E Business meeting on the future
scopes of the Commission.

Future International Meetings Related to Electromagnetic Noise1.
