| Abstract: | A two-dimensional electromagnetic simulation model is used to investigate the production of whistler waves in connection with electron beam experiments in space. The spectrum is observed to peak near 0.7 ωe, and the conversion efficiency of beam energy to whistler waves is about 5 × 10−5. The whistlers can be trapped in a density trough extending out from the spacecraft and experience ducted propagation. |
