| Outline of Final Research Achievements |
In order to evaluate the cellular effects under the magnetic field resonance transmission at the 400 kHz band, we had worked on resonant power transmission coil production. Covered rectangular copper wire was used with a width of 5 mm and a thickness of 0.4 mm. Both the power transmitting side and the power receiving side coil were made as a two-layer structure. Power feeding to the power transmission side coil was made by a direct feeding method connected to the respective ends of the laminated coils. The characteristics of this magnetic field resonance power transmission coil were measured using a network analyzer. From this result, we confirmed that the resonance frequency was 422 kHz and the transmission efficiency was over 65%. In addition, we had estimated that the magnetic field intensity at the center between transmitting and receiving coils was 480 to 560 A / m, which is more than 6 times the ICNIRP guidelines of 80 A / m, using the electromagnetic field simulator
