Resonant frequency shift of complementary split ring resonator in terahertz region

The goal of our research is to convert the frequency of terahertz waves, and for this purpose, we explore resonant frequency shifts of split ring resonators (SRRs) in this study. SRRs have some resonances corresponding to its geometrical parameters [1]. We attempt to shift the resonant frequency of the SRR with the change of resonant modes by external effects. For our purpose, SRRs are needed to have high quality factor and wideband shift of the resonant frequency. In this study, we investigate the transmission spectra change of the complementary SRRs on thin Si substrate.
