Zusammenfassung:The reflection and transmission coefficients of metafilms composed of U-shaped resonators were obtained in the frequency range of 0.1 - 1 THz by numerical finite-element simulation method. The side length, the gap depth and the period of resonators were proportionally scaled. The experimental spectra of the transmission coefficients for metafilms with U-shaped resonators were received. The re-tuning of the resonant modes was shown from 0.12 till 0.51 THz at the geometric parameters scaling.
