Hybrid terahertz metamaterial structure formed by assembling a split ring resonator with a metal mesh

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. Our experimental studies on the composite structure indicate that the coupling of the SRR and metal mesh significantly contribu...

Summary: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. Our experimental studies on the composite structure indicate that the coupling of the SRR and metal mesh significantly contribute to the transparency at the terahertz range, Moreover, we experimentally demonstrated the verity of transmission peak of this structure by changing the relative positions of the SRR and the metal mesh. The simulated electric field redistributions support the dependence between position of the two components and the transmis- sion response. This study is the first to report a hybrid metamaterial structure consisting of an SRR array and a metal mesh within a unit cell. The designed process and resonance characteristics of this composite structure make it an excellent candidate for developing tunable terahertz components via integration with the MEMS （Micro Electronic Mechanical System） technolo- gY.
