Figure 4
Schematic diagram of (a) experimental setup and (b) image of a portion of the fabricated sample. (c) Measured transmission amplitudes of the deflector from 0.25 to 1.4 THz under x-polarized normal incidence as the receiving angles are 0°, 12°, 14°, 16° and 18°. (d) Measured transmission amplitudes of the deflector against the receiving angle at 0.3988, 0.4025, 1.2477 and 1.2513 THz. (e) Experimental results of the deflection effect with respect to the frequency (x-axis) and deflection angle (y-axis). The simulated and calculated results are plotted as pink pentagrams and yellow dots, respectively. The inset shows the portion from 1.1 to 1.4 THz with enlarged intensity.
