FIG. 1.

(a) Scanning electron microscopy micrograph of the split ring resonators fabricated on GaAs; (b) schematic diagram of the experimental arrangement in reflective geometry for SRRs with aqueous solutions; and (c) experimental setup for THz-TDS measurement.

Image of FIG. 2.
FIG. 2.

Typical reflective THz time-domain waveforms from SRRs/GaAs. The signals observed at a shorter delay time (∼4 ps) originate in reflection from the N2/GaAs interface, while those of a longer delay time (∼20 ps) come from the SRRs/solution interface.

Image of FIG. 3.
FIG. 3.

Modulated reflective THz response of the LC resonances by (a) ethanol-water mixture, and (c) aqueous solution of NaCl of different concentrations. The signal is normalized to the response of SRRs with pure water; The ΔPV of the LC resonances as a function of (b) the ethanol-water mixture with the concentration specified as a volume ratio of ethanol to water, and (d) the aqueous solution of NaCl.

Image of FIG. 4.
FIG. 4.

Simulated THz reflective spectra of (a) ethanol-water mixture and (b) aqueous solution of NaCl in different concentrations. Simulated ΔPV as a function of the dielectric constant of (c) the ethanol-water mixture and (d) the aqueous solution of NaCl.
