| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | One of the problems in wireless power transfer using magnetic resonant coupling is that the ingress of metallic foreign objects between the coils causes power loss and deteriorates the transmission efficiency. For locations where it is necessary to transmit power through a reinforced concrete wall that utilizes rebar, one of the metallic foreign bodies, it is necessary to consider transmission based on the assumption that the rebar has been pre-infiltrated. In this study, it was tested that the difference in the effect of different transmission distances, rebar spacing, and rebar isolation, and investigated methods to improve the efficiency. As a result, we succeeded in improving the efficiency by isolating the intersection of the rebars, which reduced the shift of the resonance frequency. | |
