In this paper, we present the design and simulation results of the Terahertz Subwavelength Confinement Waveguides (TSCW) operating at 1 THz. The design of the TSCWs includes CPW-to-TSCW transition circuits and the Spoof Surface Plasmon Polariton (SSPP)-based waveguides. The best-case simulation results exhibit return loss and insertion loss of -13.86 dB and -1.72 dB for the back-to-back (b-to-b) transition circuit and -26.5 dB and -4.66 dB for the TSCW with a total length of 267 um at 1 THz, respectively.
