Design of Tunable Terahertz Metamaterial Sensor with Single- and Dual-Resonance Characteristic
We present two types of refractive index sensors by using tunable terahertz (THz) metamaterial (TTM) based on two concentric split-ring resonators (SRRs) with different splits. By modifying the distance between SRRs and substrate, TTM shows tunable single- and dual-resonance characteristic. The maxi...
