Figure 3. A comparison with THz measurements and FDTD simulations, and THz images obtained with the fructose antenna.

Figure 3

(a) The changes in the maximum values of the normalized transmittances are plotted for fructose and D-glucose as a function of the molecular concentration level, measured using the fructose antenna. (b) Simulation results of cladding thickness-dependent maximum transmittances for two samples having absorption peaks at 1.7 THz and 1.4 THz are shown. The dashed lines are exponential fittings for all cases. (c) A photograph of the nano-antenna with 250 mg/dL of dropped fructose (upper-right corner) and D-glucose (lower-left corner) stains. (d) A normalized THz transmittance image through the fructose antenna with the two samples.
