Distribution of THz electric field in the split-ring resonator metamaterials based on the thin film geometry

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.

Frequency Wave

Second-harmonic generation in split ring resonator multilayer nanostructure is studied with the finite-difference time-domain (FDTD) method. The fundamental frequency wave and the second-harmonic generation at the resonant absorption wavelength are highly localized in the dielectric layer, and the absorption peak is sensitive to dielectric constant of the dielectric layer. Under the excitation of the plasmon resonances mode, the strong local field induces an expected increase of the second-harmonic generation with conversion efficiencies 10−6-10−7. The distributions of fundamental frequency electric field and second-harmonic electric field inside the central dielectric layer region are also shown.
