FIG. 1.

(Color online) Schematic showing the creation of metallic defects in a 1D PC by inserting a single metallic wire (or an array of parallel metallic wires) into the air-gap defect of the PC and the characterization of the metallic defect modes by THz-TDS measurements.

FIG. 10.

(Color online) Calculated electric field distributions of the three resonant modes located at 980 μm (a), 1022 μm (b), and 1113 μm (c) for the PC containing two parallel metallic wires (d = 300 μm) separated by 1 mm for TE-polarized waves.

Image of FIG. 11.
