In this paper, spoof surface plasmon polariton (SPP) is integrated in the closed substrate integrated waveguide (SIW) structure and a novel hybrid SIW-SPP guided-wave transmission line (TL) is proposed. In this design, the surface wave mode of SPP can be excited and transmitted inside the closed str...
