We investigate the transmission properties of a metamagnetic structure, the so-called cut-wire pair (CWP), using the transfer-matrix method and the finite integration technique. The electric and magnetic resonances of the CWP structure are demonstrated by the effective medium analyses. The corresponding effective permittivity and permeability are calculated from the complex scattering parameters using the standard retrieval procedure. Importantly, the dependence of transmission properties and resonance frequencies on the periodicities as well as the shape of CWP are systematically examined.

The search for a simple meta-system with negative refractive index has attracted a lot of attention recently. In this paper, we study a negative refractive transmission operating at 300 GHz by using "single-atom" metamaterials which were initially designed for achieving negative permeability. The nature of the negativity is discussed extensively by the effective medium analysis and confirmed by the dispersion diagram.
