FIG. 1.

(a) Photo of SRR sample. (b) Experimental setup of terahertz TDS. The elements in the dotted line indicate that these are enclosed in the vacuum chamber. Laser: Ti: sapphire laser; BS: beam splitter; RM: reflecting mirror; TF: terahertz emitter; PE: pellicle; PM: off-axis parabolic mirror, which is used to collimate and focus the terahertz radiation pulse; CH: chopper; SM: sample stage; DE: terahertz detector; QP:1/4 wave plate; WS: Wollaston prism; BL: balance diode; Lock-in: lock-in amplifier.

Image of FIG. 2.
FIG. 2.

(a) The terahertz time-domain wave transmitted through the sample in case 1. The inset shows that the electric field vector is parallel to the gap-bearing sides of SRR. (b) The terahertz time-domain transmitted wave through the sample in case 2. The left inset shows the measured reference pulse. The right inset shows that the electric field vector is perpendicular to the gap-bearing sides of SRR.

FIG. 3.

(a) Amplitude transmission spectrum in case 1 (solid line) and in case 2 (dashed line). (b) Theoretical amplitude transmission spectrum simulated by FDTD.

Image of FIG. 4.
FIG. 4.

(a) Dispersion relation of SRR (case 1). (b) Effective permittivity and effective permeability of SRR (case 1).
