Abstract

Abstract

The Finite Conductivity Wall module is verified and validated in terahertz folded waveguide traveling wave tube simulation compared with commercial software including attenuation result of cold test and gain result of hot test. The calculated results agree with each other well. Max relative error of attenuation in cold test is about 3%~4%, and max relative error of gain in hot test is about 2% with the optimal working voltage drifting relative error about 2%. In addition, the influence of geometric structural parameters on the attenuation result of cold test is also analyzed and discussed in detail.
