Electromagnetic tunneling through a single-negative slab paired with a double-positive bilayer
Electromagnetic tunneling through a single-negative slab paired with a double-positive bilayer
We show that resonant tunneling of electromagnetic fields can occur through a three-layer structure composed of a single-negative (i.e., either negative permittivity or negative permeability) slab paired with a bilayer made of double-positive (i.e., positive permittivity and permeability) media. In particular, one of the two double-positive media can be chosen …
