We propose a planar metamaterial formed by four-strip metallic resonators, which can achieve high- Q Fano resonance in terahertz regime. This terahertz planar metamaterial supports a sharp Fano resonance at 0.81 THz with 25% transmission. The resonance bandwidth of the dip is 0.014 THz with the Q -f...
