Abstract :
In this paper, the TWT nonlinear equations are newly derived by considering the higher harmonics. The nonlinear process is also simulated by the Russian simulation code TWTSNU. Compared with the simulations, the derivations of this paper have the discrepancy of about 2%, while the old equations of about 10%. Also, it can be clearly seen from this paper that the output power of fundamental harmonic decreases obviously because of the existence of higher harmonics.
