We systematically study the transmission property of metallic short-slab pair and continuous wire structure metamaterial and its dependence on the system geometrical parameters in the infrared frequency regime, using the transfer-matrix method and the commercial code, CST Microwave Studio. It is found that the passband is sensitive to the length and the thickness of the continuous wire. As the length or thickness increases, the passband is slightly extended to a higher frequency. It is also found that the dependence of the passband on the material of dielectric layer.
