Resonances inside metallic nanoslots and along metal-substrate interfaces have been investigated theoretically, which shows the fact that the transmission characteristic of a double periodic metallic nanoslot array could be manipulated by adjusting the structural parameters. A transmission structure over a wide band of infrared and terahertz waves has been proposed, with 30 dB isolation between peaks inside the infrared band and high flexibility in tuning.
