| Abstract(in English) | We have optimized various kinds of parameters such as the loading capacitors of a spiral resonator, its resonant frequency, its size, and the winding line of coils to realize high efficiency wireless power transfer under seawater, but have not fully grasped the effects that the salt water gives to resonators. Therefore, using the electromagnetic field simulation software HFSS, we started to find a loss mechanism by calculation of the electromagnetic field energy in the realistic model as possible. In addition, comparing the theoretical value based on a new model with the measured value of unloaded Q, we have studied the influence of frequency characteristics of conductivity to the loss mechanism. |
