摘要:We present a numerical simulation of frequency-agile terahertz metamaterials which incorporate semiconducting material as an integral part of the resonant elements to split ring resonator (SSR). The resonance frequency of the metamaterial can be dynamical tune through photoexcitation. The modification of capacitance at the split gap by photoexcitation results in red-shifting of metamaterial resonance frequency over 20% whereas a blue-shifting of resonance frequency over 30% is achieved by adding two portions of semiconductor into the metamaterial to get a tunable equivalent inductance.
