Abstract :
A 2.5D multifrequency large signal beam-wave reaction code of TWT based on the field theory is developed for crossmodulation and intermodulation products, in which space charge fields are obtained through solving discrete Helmholtz equations with the help of Particle-in-cell method. Two-tone experiment and simulation of L band space helix-TWT shown that a good agreement in CM and IM products.
