The influence of period between U-shaped resonators on metasurface response at terahertz frequency range

摘要: In this paper we study the influence of period between U-shaped split-ring resonators (SRRs) on trans- mission/absorbtion properties and refraction index metasurfaces in THz frequency range (0.1 - 1 THz) using experiments numerical simulations. The are formed by SRRs arrays. varies from 63 to 300 μm metasurface electromagnetic responses obtained terahertz time-domain spectroscopy. experimental results reveal shift transmission spectra for response tuning absorbtion intensity at changing. notable change refractive is shown.
