Introduction to the Ohki Laboratory, Waseda University

Prof. Yoshimichi Ohki

  • Professor Yoshimichi Ohki is engaged in both the Department of Electrical Engineering and Bioscience, and the Joint Department of Nuclear Energy at Waseda University, Japan. He received his Ph.D. in Electrical Engineering at Waseda University in 1978. He has received numerous honors and awards including the Yazaki Science Award in 1995, IEEE Fellow in 2000, the IEEE Whitehead Memorial Award in 2007 and the IEE-Japan Outstanding Achievement Award in 2010. He has published more than 320 papers in refereed journals, contributed to over 760 papers in International and domestic conferences, and has contributed to several textbooks and handbooks. In the Joint Department of Nuclear Energy, he is currently in charge of the Accelerator Applications Laboratory, where he is mainly conducting research on several topics relating to space charge behavior in insulators and applications of ion-induced birefringenece to functional optical waveguides. More specifically, space charge is the charge or electric charge carriers that are trapped and become immobile in insulating materials. They distort and locally enhance the electric field inside the material. Therefore, to know the behavior of space charge is of prime importance for every electric apparatus including electric wire and cable.
     Many pieces of electric wire and cable with a total length of more than 1,000 km are used in a nuclear power plant. Polymeric materials are used as insulating materials. Therefore, their integrity is of prime importance for the safety of nuclear power plants. Prof. Ohki is an active member of many related committees in many organizations such as OECD, IAEA, and Japan’s METI-NISA, and is now developing a new reliable non-destructive diagnostic method of cable aging. In the second topic, he is doing much research aiming at controlling optical transmission by implanting high energy ions into inorganic solid materials. So far, he has developed long-period gratings, directional couplers, polarization-maintaining fibers, and de-polarizers.
     However, his research interests are not limited in these fields, but expand to various organic and inorganic dielectric materials for many applications from nano-tech biosensors to power cables in nuclear power plants. Especially for those who want to get Ph. D. (or Dr. Eng.) degree, Prof. Ohki is one of the best supervisors, not only in Waseda University but also throughout Japan. The reason for this is that Ph. D. candidates must succeed in obtaining several his (or her) own papers refereed by reviewers and published in high-class academic journals, before proceeding to the doctoral defense. In this regard, Prof. Ohki, who has published an astonishingly large number of refereed papers in eminent journals, is truly reliable.
