資料10-ECommission E (Electromagnetic Noise and Interference) Activity Report
Sep 2020 - July 2021
Commission E in Japan is holding technical meetings and sub-committee activities incollaboration with the Technical Committee on Electromagnetic Compatibility (EMCJ) of theInstitute of Electronics, Information and Communication Engineers (IEICE), the TechnicalCommittee on Electromagnetic Compatibility of the Institute of Electrical Engineers of Japan(IEEJ-EMC), IEEE EMC Society Japan Joint Chapter and Sendai Chapter, Society ofAtmospheric Electricity Japan and some related technical groups.
New committee membersFifteen new committee members for Commission E of Japan National Committee (25th) wereapproved during the committee meeting held on 11 June on line due to the covid 19 virus
spreading. New chair, vice chair and secretaries were selected as follows:
Chair: Tomoo Ushio (Osaka University)
Vice Chair: Ken Kawamata (Tohoku Gakuin University)
Secretaries: Takeshi Morimoto (Kindai University) and Kaoru Gotoh (NICT)
Domestic academic activities of EMCJ and IEEJ-EMC:
1. Regular EMCJ Meetings
The EMCJ of IEICE had 10 regular technical meetings in the period of September 2020 toJuly 2021. These regular meetings were technically co-sponsored by IEEE EMC Society Japan
Joint Chapter and IEEE EMC Society Sendai Chapter. Three of them were co-organized withTechnical Committee on Electromagnetic Compatibility of the Institute of Electrical Engineersof Japan (IEEJ-EMC). In total 105 regular technical reports including 2 invited talks werepresented.
( http://www.ieice.org/ken/program/index.php?instsoc=IEICE-B&tgid=IEICE-EMCJ )The featuring technical topic of the October meeting was “EM Simulation, EMC andMicrowaves” and co-organized with the Technical Committee on Microwaves (MW of IEICE),Electronics Simulation Technology (EST of IEICE), and the Technical committee on Photonicsapplied Electromagnetic Measurement (PEM of IEICE). The March meeting was co-organizedby the Technical Committee on Healthcare and Medical Information Communication
Technology (MICT) of IEICE. The meeting in July 2021 was held as the annual “EMCJ Young
Researchers' Presentation Meeting” which is co-sponsored by the Japan Institute of Electronics
Packaging (JIEP) Electromagnetic Technology Committee.
2. Regular IEEJ-EMC Meetings
The IEEJ-EMC had 3 technical meetings in the period of September 2020 to July 2021.
These are technically co-sponsored with the IEICE-EMCJ and IEEE EMC Society Japan Joint

Commission E

資料10-Eand Sendai Chapters. All of these meetings were held online due to the influence of COVID-19.
There were total of 7 technical reports from the IEEJ-EMC at these three meetings.
3. Activity of sub-committees of IEEJ-EMC
As of September 2020, the following 3 sub-committees are continuing activities under thetechnical committee on the IEEJ-EMC. These are (1) Investigation committee on the health risk
analysis of electromagnetic field (July 2014 – June 2016 / June 2016 – May 2020 (Phase 2) /May 2020 – April 2023 (Phase 3)), (2) Investigation committee on Systems and EMC in theIoT (April 2018 – March 2021), and (3) Investigation committee on Measurement andevaluation technology for EMC elucidation of ESD phenomena (Oct. 2020 – Sept. 2023).
As of July 2021, the Investigation committee on Systems and EMC in the IoT (April 2018 –March 2021) has completed its activities in March 2021 and is now preparing issue the technicalreport. And a new investigation committee was established which is (4) Investigation committeeon trend survey of advanced electromagnetic field exposure evaluation basic technology (July2021 – June 2024).

Domestic academic activities in the field of natural electromagnetic noise:Commission E members in Japan working actively in the field of natural electromagnetic
noise are presented their research results in the following meetings and/or symposiums.
1. International conference/workshop(1) American Geophysical Union (AGU) Fall Meeting 2020
This international conference is held every year in December in USA and the largest one in
the field of Earth and space science. In 2020, the meeting was held on line due to COVID 19
spreading from 1 to 17 December. About 25400 scientists from 107 countries including US,Canada, UK, Japan, China, etc. attended and about 12000 posters are presented with 1.1 million
views on line. Several URSI-E committee members were presented the papers in the field of
atmospheric electricity and seismo-electromagnetics.
2. Domestic conference/workshop(1) Society of Atmospheric Electricity of Japan (SAEJ) annual meeting 2020
This is an annual meeting held in January. In 2020 fiscal year, the meeting was held totally online for the first time in the 59 years history of the society on 8 and 9 January and 54 scientificpapers were presented. Several URSI-E committee members were presented the papers relatedto the areas covered by Commission E.
