A method of realizing multiband left-handed metamaterials (MB-LHMs) was presented. By alternatively stacking arrays of unit cells with different geometrical dimensions, the combined structures exhibit multiple LH passbands. As an example, a typical MB-LHM was designed, fabricated, and investigated numerically and experimentally. Both the simulation and experiment results show that the MB-LHM has three alternatively left- and right-handed passbands, of which two are LH ones.

    Metamaterials are artificial structures that can be designed to exhibit specific electromagnetic properties that are not in the nature. In this paper, we design a directional coupler, based on the theory of the split-ring resonators (SRRs), and the complementary SRR (CSRRs). The experiments and...
