Electromagnetic-wave tunneling through negative-permittivity media with high magnetic fields

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.
