Abstract(in Japanese) (See Japanese page)
Abstract(in English) Because real rivers or lakes are surrounded by soil, there is concern about the impact of soil on wireless power transfer system. Simulations are conducted to determine the extent to which the electrical properties, which vary greatly depending on the nature of the soil and its moisture content, affect the system. In addition, the electrode arrangement is optimized to avoid the influence of soil on the system. Finally, the validity of the simulation results is confirmed by comparing the simulation results with the measured results from a simplified experimental setup.
