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.
我们提出了一种方案，用于在由负介电常数和负磁导率超材料组成的一维无序多层结构中诱导透明度。首先，精确推导了透明度条件的解析表达式，为我们提供了一幅图景：如果指数增长波能够补偿指数衰减波，那么在这种多共振系统中就可以实现完全隧穿。其次，采用一种补偿方法来实现这一想法，并在微波波段进行了模拟和实验，以证实理论分析。最后，我们讨论了共振耦合如何影响样品的传输特性。
