Title:  Spoof Surface Plasmon Polaritons Supported by Substrate Integrated Waveguide with Arrays of Holes

Abstract:
This work presents an approach to develop spoof surface plasmon polaritons (SSPPs) in substrate integrated waveguides (SIWs) with simple geometries (arrays of rectangular holes). Dispersion properties of both SSPPs supported by a SIW with a rectangular hole and the traditional SSPPs based on a single-conductor metallic strip with the same hole are compared. Moreover, a smooth transition built by stepped impedance transmission lines with gradient holes is designed for high-efficiency mode conversion. Consequently, an SSPP waveguide is constructed by a SIW with uniform holes and the proposed transition, and the transmission characteristics of the waveguide are simulated for validation. The simulated bandwidth can reach as high as 100.1% covering a range from 4.34 to 13.05 GHz, which shows a good agreement with the results in the dispersion diagram.
