N2 - A metamaterial (MTM) with negative effective permeability has been proposed used as an intermediate power focusing element in a wireless power transmission (WPT) network. Split ring resonators with a 0.4 mm thickness have been formed on FR4 substrate for the MTM. The proposed MTM was modelled and simulated using CST Studio Suite with the effective permeability educed from its S-parameters. The real part of effective relative permeability is μeff=-3.47 at 432 MHz. By applying the proposed MTM to a WPT link, an improvement in power transfer efficiency (PTE) and magnetic field distribution can be achieved. When the overall distance between the transmitter and receiver is 40 mm, the PTE improves from 0.25% to 72.25% at the operating frequency.
