Abstract: Negative permittivity can be realized from the periodic unit cells of the metallic bar structure, and the effects of the length and the width of the metallic bar on negative permittivity is discussed. Through arraying two unit cells along the direction of the wave vector k , the negative permeability can be achieved from a strong resonance response of the two metallic bars to external magnetic field, so a one-dimensional left-handed metamaterials is obtained. The left-handed properties can also be obtained if magnetic boundary conditions of the two unit cells are interchanged with those of wave ports, but electrical boundary conditions are unchanged, i.e., the wave vector k rotates by 90°. So a two-dimensional left-handed metamaterials is achieved.
