[IEEE 2018 Cross Strait Quad-Regional Radio Science and Wireless Technology Conference (CSQRWC) - Xuzhou (2018.7.21-2018.7.24)] 2018 Cross Strait Quad-Regional Radio Science and Wireless Technology Conference (CSQRWC) - A New Design for Spoof Surface Plasmon Polaritons Using Periodic Holes Etched on the Stripline

摘要： In this paper, a symmetrical ultrathin spoof surface plasmon polaritons (SSPPs) is realized based on the traditional coplanar waveguide (CPW), which can achieve multi-band high-efficiency transmission by employing the periodic holes etched on the middle stripline. Physical mechanism of the proposed SSPPs is explained by using the dispersion curves and electric field distributions. The measured results have a good agreement with the simulated ones, which indicate that the proposed SSPPs will be potentially very useful for microwave applications.
