Abstract

Design and analysis of a slow-wave structure potentially applicable to high power traveling-wave tube (TWT) amplifiers at millimeter-wave frequencies are presented. The circuit characteristics including dispersion relation is predicted. Hot test particle-in-cell (PIC) simulation results will be described employing VORPAL that is based on the conformal finite difference time domain (CFDTD) method.
