Introduction

Our daily lives are surrounded by electromagnetic wave. It includes not only radio wave utilized in the data transmission but also heat radiation from our body and sunlight. We are widely conducting basic & applied researches with the aim of social contribution using the electromagnetic field; Basic researches are wireless power transfer under water and development of the resonator with high quality factor used in RF filter. Applied research is realization of the two-way communication module that can work by wireless power transfer.

Wireless Power transfer under SeaWater

In order to contribute to our marine resources development, our laboratory is aimed at the establishment of system that can wirelessly transmit the power to the remotely-operated vehicle under seawater. As one of the necessary technologies, there is wireless power transfer of kW power, and the use of electromagnetic fields as a solution has attracted attention. However, since nobody elucidates the electric properties of water/seawater under the circumstance of kW power yet, the structure of the electrodes used in the WPT under water is not optimized. Therefore, we are developing the method to measure them and the electrode structure suitable for WPT under water.
