讲座人介绍
Koichi Ito received the B.S. and M.S. degrees from Chiba University, Japan, and the Ph.D degree from Tokyo Institute of Technology, Japan.  He served as Deputy Vice-President for Research and Director of the Center for Frontier Medical Engineering, Chiba University.  He is currently a Professor Emeritus and Visiting Professor at the Center for Frontier Medical Engineering, Chiba University. 
His main research interests include small antennas for mobile communications, microwave antennas for medical applications such as cancer treatment, research on evaluation of the interaction between electromagnetic fields and the human body by use of phantoms, and antenna systems for body-centric wireless communications.  
Dr. Ito is a Life Fellow of the IEEE and a Fellow of the IEICE, Japan.  He served as Chair of the IEICE Technical Committee on Human Phantoms for Electromagnetics, Chair of the IEEE AP-S Japan Chapter, an Associate Editor for the IEEE Transactions on Antennas and Propagation, an AdCom member for the IEEE AP-S, a Distinguished Lecturer for the IEEE AP-S, General Chair of IEEE iWAT2008, Chair of the IEICE Technical Committee on Antennas and Propagation, a member of the Board of Directors, the Bioelectromagnetics Society (BEMS), a Councilor to the Asian Society of Hyperthermic Oncology (ASHO), General Chair of ISAP2012, and a Delegate to the European Association on Antennas and Propagation (EurAAP).  
He currently serves as a Vice-President of the Japanese Society for Thermal Medicine (JSTM), Vice-Chair of URSI Commission K, and as IEEE AP-S President for 2019.
讲座内容
Recently, numerous wearable wireless devices have been widely used for different purposesin our daily life. Also, various implantable wireless devices have been developed and become available for monitoring, stimulatingor identification systems. Unlike conventional wireless devices, wearable or implantable wireless devices are used on or in the human body. In this sense, body-centric wireless communications (BCWCs) have become a very active and essential area of research. On the other hand, radio-frequency or microwave medical devices used for cancer treatment and surgical operation have completely different functions. However, they are used on or in the human body. In terms of antennas installed inside the devices, such medical devices have lots of similarities to BCWCs. 
To design properly and to make the best use of specific antennas for different wireless devices, it is important to treat them as human-centric antennas.  In general, the problem of an antenna placed on or in the human body can be treated as a so-called “boundary value problem” where the human body can be considered as a complex lossy medium.Although this concept is essential,in reality and simplicity, an individual case is mostlytreated appropriately in a specific manner by numerical simulation such as the FDTD technique. 
In this presentation, after brief introduction, a general concept of how to treat antennas and a specific approach to wearable antennas are overviewed.  Then, a few examples of wearable and implantable antennas are introduced.  Finally, some challenges of human-centric antennas are highlighted.
