We pre­sent our nu­mer­i­cal ap­proach and pre­lim­i­nary re­sults of the cal­cu­la­tions of whistler and X-mode wave gen­er­a­tion by a bunched elec­tron beam in space. The ar­ti­fi­cial gen­er­a­tion of whistler and X-mode plasma waves in space is among the can­di­date tech­niques to ac­com­plish the ra­di­a­tion belt re­me­di­a­tion (RBR), in an ef­fort to pre­cip­i­tate en­er­getic elec­trons to­wards the at­mos­phere to re­duce their threat to low-Earth orbit satel­lites. Free-space prop­a­ga­tion of an elec­tron pulse in a con­stant back­ground mag­netic field was sim­u­lated with the CST par­ti­cle-in-cell (PIC) solver, with the tem­po­ral evo­lu­tion of the beam recorded. The Spec­tralPlas­ma­Solver (SPS) was then mod­i­fied to use the recorded elec­tron pulse prop­a­ga­tion to cal­cu­late the real-time plasma waves gen­er­ated by the beam. SPS sim­u­la­tion re­sults of the wave gen­er­a­tion for the up­com­ing Beam-PIE ex­per­i­ment as well as an ideal bunched elec­tron beam are shown.
