Ozsahin, G.Unutmaz, M.A.Unlu, M.2025-03-222025-03-2220192429-1390https://hdl.handle.net/20.500.11851/12181We present a circuit model for the spoof Surface Plasmon Polaritons (sSPP) waveguides for the terahertz band. The circuit model uses the theorical calculation and optimization of the circuit elements in terms of the groove parameters. Here, we first simulate the sSPP waveguide by changing the groove dimensions that are the depth, aperture, and periodicity and extract the values of the circuit model parameters. Finally, we present the comparison of the proposed circuit model with the measurements. © 2019, META Conference.
