Study on the Electromagnetic Responses of Split Ring Resonator in THz Regions

Abstract

By using the numerical simulation techniques, the response characteristics of single split-ring resonator (SRR) in a broadband terahertz region are analyzed. We examine the transmission and dispersion characteristics of the SRR and show that there are different resonances while changing the orientations of electric field vector relative to the gap-bearing sides. Two significant resonances corresponding to electric response and magnetic response will be observed while the electric field vector perpendicular to the gap-bearing side, and only one electric resonance occurs when the electric field vector parallel to the same side. This will be a reference to design the possible terahertz metamaterials.
