摘要: 分析了平面电压波与一对2维电感加载传输线和电容加载传输线介质板的相互作用，在共轭匹配的条件下，推导出了传输线介质板内外的电压分布，并着重讨论了倏逝波和传播波波数的取值方法。仿真结果显示，这对介质板前面的电压幅度和相位与后面的电压幅度和相位是相同的，这说明了电压波的每一个空间傅里叶成分，包括电压传播波和电压倏逝波，能够完全通过这对共轭匹配板，表明在板中存在很强的隧道效应。Abstract: The interaction of the plane voltage wave with a pair of 2-D inductor loaded and capacitor loaded transmission line metamaterial slabs is analysed. Under the conjugate matched condition, the voltage distributions inside and outside such paired slabs are derived. In particular, the z-directed wavenumber of the evanescent and propagating voltage wave is discussed. The simulation results show the voltage phase and magnitude at the front face of the pair are the same as that at the back face of the pair, which manifests that each of the spatial Fourier components, including propagating as well as evanescent waves, can completely pass through the conjugate matched slabs, indicating the complete tunneling effect．
