Abstract

We present a new time-domain algorithm designed for self-consistent 3D simulation of the nonlinear interaction between an electron beam and RF fields in planar slow wave structures, based on a modified alternating direction implicit (ADI) finite difference time domain (FDTD) time advance scheme. The algorithm forms the basis of a new simulation code, NEPTUNE.
