我们证明了电磁波可以以单位透射率通过夹在两个相同的高介电常数板之间的负介电常数介质板，尽管每个板几乎是不透明的。这种类型的透明伴随着高磁场，并且对入射角具有鲁棒性。微波实验结果与时域有限差分模拟结果非常吻合，成功地实现了这一思想。
We demonstrate that electromagnetic waves can transmit with unit transmittance through a slab of negative-permittivity media sandwiched between two identical slabs with high permittivity, although each single slab is nearly opaque. This type of transparency is accompanied by high magnetic fields, and is robust against incidence angles. Microwave experiments, in excellent agreement with finite-difference-time-domain simulations, are performed to successfully realize this idea.
