Abstract
We discuss the wave properties of some exotic materials and photonic band gap structures composed of them. The exotic materials under consideration are so-called backward-wave (BW) media or Veselago, media, whose both permittivity and permeability are negative, and so-called wire media with negative permittivity. Considering finite-period one-dimensional PBG structures, whose each period consists of one layer of a usual material and one layer of a BW-medium, we have found that the usage of a negative material makes it possible to dramatically widen the band gap of one-dimensional layered PBG structures. We have studied waveguiding properties of a plane two-layered waveguide, whose one layer is a usual magnetodielectric, but another one is a slab of a BW-material, and have shown a possibility of propagation of super-slow waves in such a waveguide. We demonstrated unusual dispersion properties of photonic crystals, containing wire media described by a uniaxial dyadic of permittivity having one negative component.
