In this review paper we discuss various possible physical realizations of artificial media with negative real parts of material parameters (wire media, split-ring resonators, omega and chiral particles, active composites). The physical phenomena behind the effect of negative parameters are explained, and analytical models for the material properties are given. Further , some simple electromagnetic systems which contain slabs of double-negative materials are studied: two-layer waveguides and one-dimensional electromagnetic crystals. Unusual properties of waves in these structures are discussed. The review describes results obtained mainly in the Radio Laboratory of the Helsinki University of Technology.
