Abstract

Abstract

The most commonly used method was adopted to calculate the conductivity loss. This paper analyzed two kinds of theory formula to calculate the effective conductivity, and fabricated the folded waveguide slow-wave structure for testing. The test result shows that the effective conductivity of 0.14 THz folded waveguide structure in oxygen free copper is 4107 S/m when the surface roughness is 0.3 m, which is not consistent with the theory calculation. Finally, the reason for this discrepancy was discussed, and a modified theoretical formula was put forward.
