Guiding properties of metamaterials

This paper is devoted to detailed research of an opportunity to use modern metamaterials for an efficient guiding of electromagnetic waves of various ranges (mainly: giga- and terahertz). The following basic questions are considered: the true surface waves [1] guided boundary of the metamaterial; the surface waves guided by layers of a metamaterial; the localized waves in lattices of resonance microelements. The special regard is devoted to mechanism of formation backward waves in discrete systems.
