This paper explains a movement of 2022-2023. Agenda is as follows. Technical Committee on Frontier in Education Cooperation with Ethics Committee, Cooperation with Committee on Social Engagement, Prospect, and Member. "Economic new society" needs "new education" suitable for it. And educational change leads to change of "theme in our technical committee".

The main objective of HEE is to examine the direction in which electrical engineering should move in the years ahead by studying the past. Electrical engineering history constitutes the basis of technologies that we should develop. It is the starting point from which we should approach the future. This paper introduces recent activities of the committee.

This report briefly presents activities of Technical Committee on Electromagnetic Theory (EMT), IEEJ. Our committee is now implementing the activities on 2023, which includes three times of the technical committee meeting and four times of technical committee conference. The report also contains three research topics presented in the technical committee meeting on EMT.

The technical committee on electromagnetic compatibility (EMC) was established under the Fundamentals and Materials Society (FMS), the Institute of Electrical Engineers in Japan (IEEJ) in 1999. Since then, research and investigation related to this field have been conducted actively in the committee. In this report, trend and current activity in the research field of electromagnetic compatibility are summarized.

This report introduces recent activities of the Technical Committee on Electrical Discharges, Plasma, and Pulsed Power (EPP). The major research subjects and aims of the technical committee on EPP, and the recent activities of the technical committee, such as technical meetings, international conferences, investigation committees are reported.

This article reports the topics of the field in light application and visual science, the activities of the technical committee (TC-LAV) and the introduction of research of technical meeting on light application and visual science of IEEJ.

The IEEJ Technical Committee on Instrumentation and Measurement has explored key technologies in this field through technical meetings and research committees. Its recent activities and some leading research results are presented.

This paper reviews the latest trend and front line of research activities in the field of dielectrics and electrical insulating materials (DEI) according to the papers presented in the 10th International Symposium on Electrical Insulating Materials (ISEIM2023) held by the Technical Committee of Dielectrics and Electrical Insulation (TC-DEI), IEEJ, on Sept. 24 - 28, 2023, at Kunibiki Messe, Matsue-city, Shimane, Japan, as an in-person meeting. The recent activities related to TC-DEI are also introduced briefly.

In this article, we report recent advances in metallic and ceramics materials technologies. The forefront of the informatics application examples, such as data-mining, machine learning, neural network model, searching for new superconducting materials, and materials/process/measurement informatics are introduced.

As new phenomena regarding the interactions between light, heat, electricity, and magnetism are discovered, the investigation to understand the mechanisms are actively carried out as well as the development of new high-performance devices that utilize such the interactions. This paper briefly describes research trends and applications regarding the interactions between light and magnetism, and between heat and magnetism.

This paper describes a QAM signal evaluation method in a radio communication evaluation system based on under-sampling. Although frequency elements generated by quadrature demodulation can be calculated using QAM symbols on a constellation, this technique requires a symbol synchronous trigger. Our proposed method has a software triggering technique that can extract the symbols regardless of the frequency difference. Numerical simulation with 16QAM showed good synchronization between the trigger and the measured waveforms. In addition, the results of demonstration experiment using 16QAM with carrier frequency of 28 GHz showed the practicality of the proposed method by drawing an eye pattern and a constellation. In conclusion, we show the possibility of high-resolution and low-cost measurement in QAM signals with mmWave carrier frequency.

In this paper we measured the electrical potential distribution of surface dielectric barrier discharges caused by alternating voltage in synthetic air and nitrogen using the Pockels effect. It was shown that different potential distributions of filament thickness and length are generated in synthetic air and nitrogen. A filament analysis based on mathematical morphology was performed to quantify the geometric characteristics of the filaments produced in each gas atmosphere. The results show that the discharge filament thickness and the entropy in the filament direction depend on the oxygen ratio and the magnitude of the applied voltage.

In this study, the authors proposed the millimeter-wave band transmission coefficient measurement setup using dielectric lenses made from foam material. In addition, the transmission characteristics of the dielectric material were evaluated by measurement and transmission line calculation.
