摘 要：正Based upon the model of Rowe’s transmission -line equivalent circuit,using the maximal common submultiple fundamental frequency,a 3-dimensional（3D） multi-signal nonlinear model of beam-wave interaction in a helix traveling-wave tube （TWT） has been *** 3D model describes 2D RF fields,3D ac space-charge fields and 3D ac electron *** model has been implemented in the HTWT3D code,which can calculate any number of simultaneous signals,including input signals and their intermodulation *** from the HTWT3D code are shown to compare with measurements of output powers *** power.
