The schematic diagram, dispersion properties, and Eigen-mode field distributions of the digital SSPPs.

Caption

(a) The schematic diagram of the prototype of the digital SSPP waveguide, which is supported by the direct interaction between the incident wave and digital coding. (b) The schematic diagram of a single digital SSPP unit, which is described by the period p = 3.2 mm, strip width w = 0.5 mm, slit width s = 0.45 mm, height of below metallic bar h1 = 3 mm, and height of upper metallic bar h2 = 2.8 mm. (c) The simulated dispersion curves of the digital SSPP unit with different states. (d-f) The Eigen-mode field distributions of the digital SSPP units with '1' state (d & e) and '0' state (f) at 7.2 GHz (d & f) and 10 GHz (e).
