Abstract

The modeling, simulation, and analysis of a ladder type millimeter-wave traveling-wave tube (TWT) slow-wave structure (SWS) are presented. The simulation contains both cold and hot tests using VORPAL, a particle-in-cell (PIC) simulator that uses the conformal finite difference time domain (CFDTD) method. Beam design, dispersion, gain, and particle analysis of the ladder circuit are described.
