Design and Analysis of a Novel Metamaterial Structure Realized in Low-Frequency Band

In this paper, the double negative metamaterial is designed and analyzed using finite element method. Most of the structure of metamaterial is applied in radar stealth technology and superlens. Compared with the traditional material, the metamaterial can focus on electromagnetic waves, which can improve the wireless power transfer (WPT) system. In previous research, the metamaterial always operated in GHz and THz which is not suitable for the WPT system. To address this problem, a novel structure of metamaterial which works in MHz is proposed. The simulation results indicate that the novel structure of metamaterial can achieve negative permeability and negative permittivity at about 50 MHz.
