摘要

超材料在近场导引和操纵方面的巨大潜力已被证明是非常有用的。在微波频率范围内，通过实验验证了理论揭示的金属丝超材料板内倏逝谐波的显著增强效应。这种现象源于驻波的共振泵送，而驻波在板内被转换成倏逝波。我们发现实验数据、数值模拟和理论吻合得很好。并展望了一些超材料在磁共振成像系统中的应用。

Manipulation the near field with wire metamaterials

Metamaterials have been proved very useful for their high potential in guiding and manipulating of near fields. A theoretically revealed effect of the significant enhancement of evanescent harmonics inside a wire metamaterial slab is experimentally verified in the microwave frequency range. The phenomenon originates from resonant pumping of standing waves into which evanescent waves are converted inside the slab. We find a good agreement between experimental data, numerical simulations and theory. Also some metamaterials applications for magnetic resonance imaging system are viewed.
