Electromagnetic wave propagation in waveguide with layered-periodic walls

Recently devices using periodic structures (superlattices) have received a great deal of attention due to their peculiar properties. In analogy with the allowed zone and forbidden zone for electron moving in periodic potential, in the case of periodic structure the allowed zone and forbidden zone for the electromagnetic waves are generated. In superlattices wave can propagate just in the allowed zone. In the considered structure, the guiding propagation is possible both for the smallest and biggest permittivity values of the guiding layer in comparison with the permittivity of the periodic structure layers. The surface waveguide is effective because the penetration depth is the least. When the intensity transferred within the layer "g" could become nearly equal zero and all energy flow transferred into the waveguide walls is also possible.
