Abstract

It is impossible to ignore the influence of S-parameter characteristics in THz folded waveguide slow wave structures. In this paper, the relation between calculated period numbers and S-parameters is considered, the effect of variations of folded waveguide slow wave structures on loss is discussed, and the influence of roughness on loss is present. The loss of 0.22 THz standard rectangular straight waveguides is measured to certify theoretical analysis. Finally, based on test of the machined 0.22 THz folded waveguide slow wave structures, we obtain the transmission and loss characteristics of these slow wave structures.
