Excitation of electron holes and electron wave pulses is investigated numerically on a single-ended plasma by computer simulation using a particle model. The transverse effects are taken into account by introducing the perpendicular wavenumber on the Poisson equation. Increase on the plasma potential on front of a plasma source, resulting from propagation of the rarefaction pulse from an end boundary, gives rise to the excitation of electron holes, while the rarefaction pulse reflects back as the compression pulse toward the boundary. The qualitative properties are on good agreement with experiment.
