〈Name of award and short explanation about the award〉
IEICE Technical Committee on Wireless Power Transfer: Young Researcher Award
Young Researcher Award is given to presenters under the age of 33 who present excellent papers in the regular workshops of IEICE Technical Committee on WPT.

〈About awarded research〉
Kentaro Matsuura, Daisuke Kobuchi, Yoshiaki Narusue, and Hiroyuki Morikawa, "Communication-Less Receiver-Side Resonant Frequency Tuning for Wireless Power Transfer Using Magnetic Resonant Coupling, " IEICE Technical Report, WPT2020-26, Dec. 2020.
Magnetic resonant coupling wireless power transfer is expected to be applied to recharge electric vehicles and mobile devices since it can provide highly efficient power over a transmission distance of up to approximately 1 meter. However, the presence of metal, water, etc. in the vicinity of the power receiver causes the resonance frequency of the power receiver to change, resulting in a decrease in the efficiency of wireless power transfer. In this study, we have developed a communication-less receiver-side resonant frequency tuning mechanism that cancels out the effects of resonant frequency fluctuations using a variable reactor composed of purely electronic components. We have realized a wireless power transfer system that enables highly efficient and stable power transfer even under less than ideal operating conditions.

〈Your impression & future plan〉
I am very pleased to receive this honorable award. For the widespread use of wireless power transfer systems, I believe that it is necessary to enable stable power transfer in any environment. In the future, I would like to demonstrate the effectiveness of our proposed method in applications that are more in line with actual settings.
