Outline of Final Research Achievements

Characteristics and operating principle are examined by the equivalent circuit analysis. An equivalent circuit was considered first and determined that each element constants. We have investigated the effect of each element parameters for the transmission efficiency. It was confirmed that the effect of the Q value of L and C is exactly equivalent for transmission efficiency and transmission distance is extended to be appropriately adjusted the load resistance and frequency. On the other hand, the reduced capacitance between metal plates of the antenna is increasing the transmission efficiency was found. Furthermore, near field control of the receive antennas additional phase lines, were found to be possible by the adjustment. Particularly "power saving Concierge", it operates as a function of a more convenient system contributing to power savingsThis is a special performance of this method
