P2-36: Simulation of crossmodulation and intermodulation products of helix TWT using a new 2.5D multifrequency large signal code

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 experim...

Summary: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.
