Abstract

The geometrical and beam parameters were specified by synthetical analysis in the paper.Using MAFIA PIC code

3-D Folded Waveguide Slow Wave Structure was simulated.In the model

electromagnetic wave was introduced by waveguide mode;axial constant magnetic field was added to confine electron beam to avoid divergence caused by space charge effect.Based on interaction model

simulation results of W-band Folded Waveguide were derived

which could be the criterion of predicting and analyzing interaction circuit characteristics.
