Abstract
A terahertz (THz) extraordinary transmission from a complementary circular split-ring resonance (CSRR) on polyimide film is investigated via THz time-domain spectroscopy. A distinct single-peak resonance is observed due to the inductive–capacitive (LC) resonance when the THz polarization is perpendicular to the gap of CSRR. When the THz polarization is parallel to the gap of CSRR, a periodic multiple resonances phenomenon is observed. With the help of electric density distribution and surface current analysis, the origin of the frequency resonance is revealed. An asymmetric Fabry–Pérot effect of the CSRR is found to induce aforementioned periodic resonances.
