(a) and (b) Simulated far-field reflection Rpp and Rss for both incident planes along ГX (φ = 0°) and ГM (φ = 45°) direction, respectively. (c) The effect on reflection of the sectioned metallic rods at the outmost surface cell with varying length, h, as depicted in (d1). The length, varying from 185 μm to 315 μm, influences the DSS frequency, which can be understood qualitatively by a circuit model shown in the inset. The DSS dips are marked by the dotted circles for different h values. (d1–d2) Schematics of EM fields of the DSS and simulated contour plot of E-field at 0.34THz for Rpp with θ = 15°, φ = 0°, and h = 228 μm. (e) and (f) Simulated far-field reflection Rpp for h = 185 μm and h = 270 μm, respectively.
