Autorentext

Jun Shibayama received his B.E., M.E., and D.Eng. degrees from Hosei University, Tokyo, Japan, in 1993, 1995, and 2001, respectively. In 1995, he joined Opto-Technology Laboratory, Furukawa Electric Co., Ltd., Ichihara, Chiba, Japan. He moved to Hosei University as an assistant professor in 1999 and has been a professor since 2015. His research interests include the numerical analysis of electromagnetic problems, particularly on optical and terahertz devices, and plasmonics. He was the first developer of an efficient implicit finite-difference time-domain (FDTD) algorithm called the locally one-dimensional FDTD (LOD-FDTD) method.

Dr. Shibayama was honored with the IEEE Ulrich L. Rohde Innovative Conference Paper Award on Computational Techniques in Electromagnetics in 2017 and the Best Paper Award during the International Symposium on Microwave and Optical Technology in 2017. He also received the Institute of Electronics, Information and Communication Engineers (IEICE) Electronics Society Award in 2018 for his contributions to pioneering research on high-performance numerical analysis of the LOD-FDTD method. He is a senior member of Optica, a member of IEEE and of the Applied Computational Electromagnetics Society (ACES), and a fellow of IEICE.
