We propose a novel metamaterial structure operating at the terahertz band. This structure is assembled by a split ring resonator (SRR) with a metal mesh within a unit cell. Experimental and simulated studies on the composite structure indicate that the coupling of the LC resonance of the SRR and the cut-off effect of the metal mesh significantly contribute to anomalous transparency at the terahertz range. Moreover, we experimentally demonstrate the dependence of peak frequency on the relative positions of the SRR and the metal mesh. The unique resonance characteristics of this composite structure make it an excellent candidate for developing tunable terahertz components via integration with MEMS technology.
