| Abstract: | In this paper,numerical simulation of a typical Ku-band helix-based traveling wave tube(TWT) from gun all the way down to collector is presented.The full TWT geometry is imported into the CST STUDIO SUITE through CAD file.A detailed simulation procedure is demonstrated,which includes gun perveance,helix dispersion characteristic,PPM focusing magnetic field,cold RF transmission,and above all,the ultimate nonlinear particle interaction.The simulation results agree with the measurements very well in terms of i... |
