A fast stripline beam kicker and septum are used to dynamically switch a high current electron beam between two beamlines. The transport of the beam through these structures is determined by the quality of the applied electromagnetic fields as well as temporal effects due to the wakefields produced by the beam. In addition, nonlinear forces in the structure will lead to emittance growth. The effect of these issues is investigated analytically and by using particle transport codes. Due to the distributed nature of the beam-induced effects, multiple macro-particles (slices) are used in the particle transport code, where each slice consists of an ensemble of particles with an initial distribution in phase space. Changes in the multipole moments of an individual slice establish electromagnetic wakes in the structure and are allowed to interact with subsequent beam macro-particles to determine the variation of the steering, focusing, and emittance growth during the beam pulse.
