提出了一种在由负介电常数和负磁导率超材料组成的一维无序多层膜中诱导透明的方案。首先，精确推导了透明条件的解析表达式，给出了在这种多共振系统中，如果指数增长的波可以补偿指数衰减的波，则可以实现完全隧穿的图景。其次，采用一种补偿方法来实现这一思想，并在微波波段进行了仿真和实验，以证实理论分析。最后讨论了共振耦合对样品输运性质的影响。
We propose a scheme to induce transparency in one-dimensional disordered multilayers which are composed of negative permittivity and negative permeability metamaterials. First, analytical expressions for transparency condition are derived exactly, providing us a picture that complete tunneling in such kind of multiple-resonance system can be achieved if exponentially growing waves can compensate exponentially decaying waves. Second, a compensating method is used to realize this idea, and both simulations and experiments are performed in the microwave regime to confirm the theoretical analysis. Last, we have a discussion on how the coupling of resonances affects the transport properties of samples.
