Abstract(in English) | Near-field wireless transfer with inductive coupling is widely used for charging mobile devices. Spatial evaluations of electromagnetic field distribution are valuable method to improve transfer efficiency. In this study, we obtain magnetic field distributions by combining optical magnetometer and a mirror-array device and demonstrate imaging of magnetic field generated from an induction coil. A 200 turns coil receives 70 kHz magnetic field transmitted by one-turn Helmholtz coil. We considered about characteristics of receiver circuit by detected magnetic field generated from an induced current. |
