Description
Summary:Wireless power transmission using magnetic resonance is considered a key technique for cutting the last wire to electrical devices in indoor environments. We realize this concept by using multi-hop displacement of a magnetic resonator array. However, multi-hop displacement has been impractical because of the complexity of the impedance matching procedure. In this study, we have derived a simple but practical impedance matching method for multi-hop straight wireless power transmission. Our method maximizes the transmission efficiency, regardless of the number of hops in the topology. The performance of our method was evaluated by both simulations and implementation.
