Space charges influence the dynamics of free electrons present inside waveguide devices. This paper examines the effect of space charges on the multipactor discharge mechanism in the dominant transverse electric (TE10) mode rectangular waveguide components by using a developed reflected-electron-inclusive multipactor prediction algorithm. The work assumes that the system of closely spaced charges is equivalent to a total charge that is continuously distributed in the form a sheet within the waveguide gap and accordingly provides an approximate model for computing the electric field induced by same charges. Simulation results suggest that the presence of space charges within a microwave device do not counter the initiation of a multipactor discharge. This observation may be attributed to the high impact energies of the multipacting electrons which despite the electrostatic repulsion forces created by the charges are able to sustain the phase-focusing mechanism.
